News & Updates

September 21st marks World Alzheimer’s Day, a global opportunity to raise awareness about Alzheimer’s disease, the most common cause of dementia worldwide. On this day, we honor those affected and shed light on how genetics can play a role in the development of the disease. Today, we’ll explore the case of Pooja, a 68-year-old woman navigating the challenges of Alzheimer’s, with a focus on the genetic factors that might influence the condition.

Pooja is a 68-year-old retired schoolteacher. Over the past two years, her family has noticed worrying changes in her behavior. Once an organized and vibrant individual, she now struggles with simple tasks like managing her finances and remembering appointments. More recently, she has been getting lost in familiar places and repeating the same questions in conversations. Her children have been concerned by these symptoms and decided it was time to get help. When they sat down with her doctor, it became clear that she was showing early signs of Alzheimer’s Disease (AD). What worried the family even more was their knowledge of Pooja’s father’s battle with Alzheimer’s, which began in his early 70s. Two of her paternal aunts also showed signs of cognitive decline, raising red flags about a possible genetic connection.

What is Alzheimer’s Disease? Let us understand the basics.

Alzheimer’s disease is a neurodegenerative condition that leads to progressive memory loss, confusion, and changes in behavior. It’s the leading cause of dementia and affects millions of people worldwide. While there is no cure for Alzheimer’s, early diagnosis can help manage symptoms and plan for future care.

There are two primary forms of Alzheimer’s disease:

- Early-onset Alzheimer’s Disease (EOAD): Occurs before age 65 and is often linked to specific genetic mutations.

- Late-onset Alzheimer’s Disease (LOAD): Typically occurs after age 65 and is influenced by both genetics and environmental factors.

Her case aligns with Late-Onset Alzheimer’s Disease (LOAD), given her age and the gradual development of her symptoms.

Could Genetics Be at Play?

With her family history of Alzheimer’s, Pooja’s children wanted to know more about the role genetics could play in their mother’s condition—and their own potential risk.

One of the most well-studied genes related to Alzheimer’s is APOE, specifically the APOE ε4 allele. Carrying one or two copies of the APOE ε4 variant significantly increases the risk of developing Alzheimer’s disease, however, it’s important to note that not everyone with this allele develops the condition, and many who don’t carry it may still be affected.

In Pooja’s case, her family history suggests a possible genetic predisposition to Alzheimer’s, particularly linked to the APOE gene. However, other genetic factors—along with lifestyle and environmental influences—can also play a role.

What Genetic Testing Can Tell Us?

Pooja’s children, understandably worried about their own future risk of developing Alzheimer’s, are exploring the option of genetic testing. Genetic testing for Alzheimer’s Disease can provide some insight into a person’s risk, but it’s important to remember that genetics isn’t destiny. For Pooja, testing could confirm if she carries the APOE ε4 variant, helping her family understand more about the genetic component of her condition.

Testing might also be useful for her children, but there are critical considerations before pursuing predictive genetic testing:

- Ethical concerns: Would knowing their genetic risk affect their life choices or create anxiety?

- Psychological impact: How would they cope with the knowledge that they may be at higher risk of developing Alzheimer’s?

- No certainty: Even if they carry the APOE ε4 allele, it doesn’t mean they will develop Alzheimer’s. Similarly, some without the allele still get the disease.

While the test can give useful insights, it can’t provide definitive answers. THIS IS WHY WE EMPHASIZE THE IMPORTANCE OF A PRE-TEST GENETIC COUNSELLING SESSION.

How to Reduce Alzheimer’s Risk: It's Not Just About Genes

While genetics plays a role in Alzheimer’s disease, especially in families like Pooja’s, there are lifestyle factors that can influence the risk:

- Exercise: Regular physical activity, especially aerobic exercise, has been shown to benefit brain health.

- Diet: A heart-healthy diet, such as the Mediterranean diet, can also help protect the brain.

- Mental engagement: Keeping the brain active through learning new skills, reading, and socializing can promote cognitive health.

- Managing cardiovascular health: Conditions like hypertension, diabetes, and high cholesterol can increase Alzheimer’s risk, so managing these is key.

For Pooja’s children and others worried about Alzheimer’s, incorporating these healthy habits could help reduce their risk—whether or not they carry the APOE ε4 allele.

Finally, to conclude, for many families, genetics may offer clues, but it’s only part of the picture. Raising awareness about Alzheimer’s, the importance of early diagnosis, and the role of genetic and lifestyle factors can help families make informed decisions about their health.

If you’re concerned about Alzheimer’s in your family, consider speaking to a genetic counselor. They can guide you through testing options, help you understand your risk, and suggest ways to reduce it.

Remember: While Alzheimer’s can’t yet be cured, understanding its genetic and lifestyle components empowers us to take proactive steps for brain health.

Imagine a young boy named Ayaan growing up in a friendly neighborhood in Mumbai. He's full of energy, and always eager to play cricket with his friends whenever he gets a chance. But right before his fifth birthday, his parents begin to notice something different about him. They notice that he struggles to keep up while playing games, falls more often, and seems unusually tired. They get worried and take him to a doctor, where they're introduced to the world of Duchenne Muscular Dystrophy (DMD).

What is Duchenne Muscular Dystrophy?

Duchenne Muscular Dystrophy is a genetic disorder that leads to progressive muscle weakness and degeneration predominantly affecting male children. This disease is rapidly progressive and the incidence is approximately 1 in 3500 live male births in the world. It's caused by a mutation in the dystrophin gene, which is crucial for maintaining the structural integrity of muscle cells. Without a functioning dystrophin, the muscles weaken over time.

What are the Symptoms?

In Ayaan’s case, the symptoms started with difficulty in activities that other children his age found easy. His parents noticed he had trouble climbing stairs and struggled with running. His once-energetic demeanor began to change, as muscle weakness started to affect his ability to walk and play. By the age of seven, Ayaan was using a wheelchair for longer distances, and his family noticed that his calves had become unusually large—an effect of the disease known as pseudohypertrophy.

As the disease progresses, it can also affect the muscles responsible for breathing and heart function. For Ayaan, this means regular visits to specialists and ongoing monitoring to manage potential respiratory and cardiac issues.

How can you diagnose DMD?

For Ayaan, diagnosing DMD involved a series of steps:

• Clinical Examination: The pediatrician noted the characteristic signs of muscle weakness and an enlarged calf muscle.
• Genetic Testing: Genetic Testing using the technique of MLPA can identify the presence of a mutation in the dystrophin gene.
• Muscle Biopsy: This step usually can provide additional confirmation by examining muscle tissue.
• Blood Tests: Elevated creatine kinase levels were observed, indicating muscle damage.

Let's understand the Treatment and Management...

While there’s no cure for DMD yet, there are several ways to manage the symptoms and enhance quality of life:

• Medications: In Ayaan’s case, his doctors recommended corticosteroids to slow the progression of muscle degeneration and improve his strength and function.
• Physical Therapy: Regular physical therapy sessions are essential to maintain mobility and reduce the risk of contractures. Ayaan’s physical therapist helps him with exercises tailored to his needs.
• Assistive Devices: Ayaan uses a wheelchair for longer distances, and braces help support his legs and keep him comfortable.
• Respiratory Support: As the disease progresses, Ayaan may need ventilatory support to assist with breathing, although his parents hope for advancements in treatment that could delay this necessity.

Advances in Research

Gene therapy is proving promising for treating Duchenne Muscular Dystrophy (DMD). This innovative approach aims to correct or replace the faulty dystrophin gene responsible for the disease, potentially transforming the future of treatment. In India, renowned institutions and research facilities are at the forefront of this groundbreaking work, working to advance gene therapy techniques and bring new hope to patients and their families.

Living with DMD in India

For families like Ayaan, living with DMD involves navigating a complex healthcare landscape. Access to specialized care and resources can vary widely. In urban cities like Mumbai, families may have better access to medical professionals and support networks, but in rural regions, the challenges can be more pronounced.

Support organizations and advocacy groups play a crucial role in providing information, emotional support, and resources. In India, organizations such as the Muscular Dystrophy Foundation India (MDFI) work tirelessly to support individuals with muscular dystrophy and their families. There is also a Molecular Diagnostics Counseling Care and Research Centre (MDCRC) is a not-for-profit NGO working on Neuromuscular genetic disorders viz. Duchenne Muscular Dystrophy (DMD). They offer valuable resources, connect families with experts, and advocate for increased research and awareness.

Genetic Counselling for DMD

Genetic counseling provides invaluable support for families affected by Duchenne Muscular Dystrophy. It helps parents gain a clear understanding of several critical aspects:

1. Understanding the Disorder: Genetic counseling explains the causes and various types of muscular dystrophy, providing clarity on how these conditions arise.
2. Recognizing Symptoms and Progression: Counselors provide information on the typical symptoms and progression of DMD/BMD, helping families anticipate the course of the disorder.
3. Assessing Recurrence Risk: Families are informed about the likelihood of the disorder recurring in future children, which aids in understanding their genetic risk.
4. Family Planning: Genetic counseling offers guidance on family planning options, helping parents make informed decisions about future pregnancies.
5. Carrier Testing: The importance of carrier testing is emphasized, which is crucial for identifying whether family members carry the genetic mutations associated with these conditions.
6. Interpreting Genetic Test Results: Counselors assist in understanding genetic test results and provide advice on any additional testing that may be needed.

Conclusion

Duchenne Muscular Dystrophy is a challenging condition, but stories like Ayaan’s remind us of the strength and resilience that families exhibit every day. With ongoing research and support, there’s hope for better treatments and, one day, a cure. By staying informed and connected with support networks, we can help improve the lives of those affected by DMD and work towards a future where this condition no longer holds back the dreams and aspirations of individuals like Aarav.

Background

A 45-year-old female with a history of anxiety and depression has been struggling to find effective medication management. Over several years, she has tried multiple antidepressants and anxiolytics but experienced a mix of poor efficacy and significant side effects, such as fatigue, dizziness, and increased anxiety. After numerous unsuccessful attempts at finding the right medication, her doctor recommended pharmacogenomic testing to tailor her treatment.

Key Issues

1. Medication Efficacy and Safety: The patient experienced limited improvement with multiple medications while enduring adverse effects.
2. Trial-and-Error Prescribing: Repeated medication switches without clear guidance led to frustration and a prolonged untreated state.
3. Patient Quality of Life: The ongoing medication trials and adverse effects led to worsening mental health and reduced daily functioning.

Pharmacogenomic Testing and Its Role

The patient underwent pharmacogenomic testing, which analyzed several genes known to influence drug metabolism and response, including:

• CYP2D6 and CYP2C19: Genes encoding enzymes involved in metabolizing many antidepressants.
• SLCO1B1: Associated with drug transport and can impact statin-related muscle toxicity.
• SLC6A4 (serotonin transporter gene): Variants of this gene are linked to response variability in selective serotonin reuptake inhibitors (SSRIs).

Test Findings

The pharmacogenomic test revealed:

• CYP2D6 Poor Metabolizer: The patient had a genetic variant resulting in reduced CYP2D6 enzyme activity, leading to slower metabolism of certain antidepressants, such as tricyclic antidepressants (TCAs) and SSRIs like fluoxetine. This explained the side effects she experienced even at lower doses.
• CYP2C19 Ultra-Rapid Metabolizer: Increased enzyme activity for this gene meant she metabolized certain SSRIs, like citalopram, too quickly, leading to subtherapeutic levels and reduced efficacy.
• SLC6A4 L/L Genotype: This genotype is associated with a better response to SSRIs, but given the patient’s metabolism profiles, conventional SSRIs may not be optimal.

Clinical Outcome

Based on these results, the patient’s provider switched her medication to venlafaxine, an antidepressant metabolized primarily through pathways that were not impacted by her CYP2D6 or CYP2C19 status. The dosing was also adjusted to account for her pharmacogenomic profile.

Within weeks, the patient reported a marked improvement in her anxiety and depression symptoms with minimal side effects. Over the following months, she continued to improve with no need for further medication changes. Her quality of life and daily functioning returned to near-normal levels.

Summary and Recommendations

Pharmacogenomic testing provided crucial insights into this patient’s unique drug metabolism profile, allowing for personalized adjustments to his medication regimen. The intervention led to better treatment outcomes and fewer side effects, demonstrating the value of integrating pharmacogenomics into clinical practice.

Next Steps:

• Continued monitoring and possible updates to the medication plan as new pharmacogenomic data become available.
• Consideration of pharmacogenomic testing for close family members who might share similar metabolic profiles.

This case highlights how targeted pharmacogenomic testing can lead to significant improvements in personalized care, particularly in patients with complex medication needs.

Schizophrenia 

Schizophrenia is a brain disorder classified as a psychosis which is characterised with symptoms like false perceptions called hallucinations, decreased ability to function, Inappropriate emotional reactions, erratic speech and behavior, trouble with daily activities and personal cleanliness, disordered thinking and concentration. Genetics of schizophrenia is multifaceted, affecting 24 million individual worldwide with each genetic variation and epigenetic alteration contributing to the disorder. 

Genetics (vs environmental) factors plays a predominant role in the development of schizophrenia, with heritability estimates ranging from 60% to 80%. However this condition does not follow specific dominant or recessive pattern of inheritance.

Candidate Genes

Several candidate genes have emerged as key players in schizophrenia susceptibility. Among these, the dopamine-related genes, such as DRD2 and COMT, has been given considerable attention due to their involvement in neurotransmission and dopaminergic dysfunction, a hallmark feature of schizophrenia.

Additionally, genes involved in synaptic plasticity (e.g., DISC1, NRXN1) and glutamatergic neurotransmission (e.g., GRIN2A, GRM3) have been implicated, underscoring the complexity of neuronal signaling disruptions in schizophrenia pathogenesis.

Polygenic Risk Ratings: Linking the Pieces

Recent developments in polygenic risk score (PRS) analysis have made it possible to gain a more thorough understanding of the genetics of schizophrenia. Through the combination of genetic variants across the genome, PRS offers insights into the susceptibility of each individual to schizophrenia. Additionally, PRS makes it easier to identify genetic risk that is common to psychiatric diseases, revealing biological pathways that overlap and possible targets for treatment.

Pathways and Networks: Researchers are pinpointing specific gene networks involved in brain development and function that seem to be disrupted in schizophrenia. These networks are often related to:

• Glutamate and GABA signaling: Neurotransmitters crucial for communication between brain cells.
• Synaptic function: How brain cells connect and transmit information.
• Neurodevelopment: Processes shaping the brain's structure. 

Environmental Triggers: Genes alone don't dictate who develops schizophrenia. Environmental factors like childhood trauma, substance abuse, and social isolation can interact with genetic predispositions, potentially triggering the onset of the illness.  

Future Direction :

Risk Prediction: It helps to understanding an individual's genetic makeup could potentially provide an estimate of their susceptibility to schizophrenia.

As we unravel the genetic intricacies of schizophrenia, personalized approaches to diagnosis and treatment are on the horizon. Integrating genetic data with clinical parameters and neuroimaging techniques holds promise for delineating distinct subtypes of schizophrenia and guiding tailored therapeutic interventions.\

In summary, we are now a  inch closer to understanding individuals genetic code for schizophrenia. While much remains to be elucidated, ongoing research endeavors by technological advancements offer unprecedented opportunities to the molecular understanding of schizophrenia and has shaped the way for innovative treatment strategies, where interventions are tailored to the individual's genetic makeup and underlying neurobiology, ultimately offering hope for improved outcomes and quality of life for individuals with this complex condition.

PKU is an inherited metabolic disorder affects approximately 1 in every 10,000 to 15,000 newborns worldwide. It is characterised by the body's inability to properly metabolise the amino acid phenylalanine. Normally, an enzyme called phenylalanine hydroxylase (PAH) converts phenylalanine into another amino acid, tyrosine. The high levels of Phenylalanine present in PKU competitively inhibits the hydroxylation of tyrosine by tyrosinase which is the first step in the formation of the pigment melanin. However, individuals with PKU lack this enzyme or have a defective version, leading to a buildup of phenylalanine in the blood and brain. Virtually all untreated patients have IQ below 50. Despite its rarity, PKU can have significant and lifelong consequences if left untreated.

Causes of PKU:

PKU is caused by mutations in the gene responsible for producing the PAH enzyme. This gene is inherited in an autosomal recessive pattern, meaning that a child must inherit two mutated copies of the gene (one from each parent) to develop the disorder. If both parents are carriers of the mutated gene, there's a 25% chance with each pregnancy that their child will have PKU.

Symptoms of PKU:

Symptoms of PKU typically appear within the first few months of life, after the baby begins to consume phenylalanine-containing foods, such as breast milk or formula. These symptoms may include:

1. Developmental delays.
2. Intellectual disability.
3. Behavioural problems.
4. Seizures.
5. Skin rashes (eczema).
6. Lighter skin, hair, and eyes compared to family members.
7. Musty odour in the breath, skin, and urine due to the buildup of phenylalanine byproducts.

Maternal PKU :

When women with PKU who are not on a low phenylalanine diet become pregnant, the offspring are affected with maternal PKU syndrome. Congenital cardiac abnormalities, mental retardation, and microcephaly are caused by high blood levels in the mother. Thus, phenylalanine needs to be controlled with diet starting before conception.

Diagnosis of PKU:

PKU is usually detected through newborn screening tests, which are performed shortly after birth. These tests involve collecting a small blood sample from the baby's heel and analysing it for elevated levels of phenylalanine. If PKU is suspected based on the screening results, further diagnostic tests, such as genetic testing or blood phenylalanine levels, may be conducted to confirm the diagnosis.

Treatment and Management:

Early diagnosis and treatment are crucial in managing PKU and preventing complications. The primary goal of treatment is to maintain blood phenylalanine levels within a safe range to prevent brain damage and cognitive impairment. Treatment options for PKU include:

1. Dietary restrictions: The cornerstone of PKU management involves following a strict low-phenylalanine diet. This typically means avoiding high-protein foods, such as meat, dairy, eggs, nuts, and certain grains, and consuming specially formulated medical foods and formulas that are low in phenylalanine.
2. Supplementary therapy: In addition to dietary restrictions, individuals with PKU may require supplementation with specific amino acids, vitamins, and minerals to ensure proper nutrition.
3. Monitoring: Regular monitoring of blood phenylalanine levels is essential to adjust dietary therapy and ensure that phenylalanine levels remain within the target range.
4. Lifelong management: PKU is a lifelong condition, and individuals with PKU require ongoing medical supervision and support to manage their condition effectively.

Conclusion:

Phenylketonuria (PKU) is a genetic disorder that affects the body's ability to metabolise the amino acid phenylalanine. Without proper treatment, PKU can lead to serious neurological and developmental problems. However, with early diagnosis and lifelong management, individuals with PKU can lead healthy and fulfilling lives. Increased awareness, improved screening methods, and ongoing research into new treatment options are essential in improving outcomes for individuals living with PKU.

In the intricate tapestry of human genetics, certain conditions stand out for their widespread impact and intriguing history. Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one such condition, affecting millions worldwide and holding significant implications for health, particularly in regions with a high prevalence of malaria.

The Basics of G6PD Deficiency

G6PD is an enzyme encoded by the G6PD gene, located on the X chromosome. It plays a crucial role in red blood cell function by protecting them from oxidative damage. However, individuals with G6PD deficiency have lower levels or defective forms of this enzyme, making their red blood cells more vulnerable to oxidative stress.

Global Distribution and Epidemiology

G6PD deficiency is one of the most common enzyme deficiencies globally, affecting approximately 400 million people. Its prevalence is particularly high in regions such as Africa, the Mediterranean, the Middle East, and parts of Asia. Interestingly, the distribution of G6PD deficiency overlaps with regions where malaria is endemic.

The Malaria Connection

The relationship between G6PD deficiency and malaria has long intrigued researchers. Studies have shown that individuals with G6PD deficiency may have some degree of protection against malaria. This is hypothesized to occur because the lower levels of red blood cells in individuals with G6PD deficiency create an environment less hospitable for the malaria parasite, Plasmodium.

Historical Insights

The story of G6PD deficiency dates back to the 1920s when Otto Warburg and his colleague first identified the enzyme's activity. However, it wasn't until the 1950s that Ernest Beutler and his team made significant breakthroughs, linking G6PD deficiency to episodes of acute hemolysis triggered by certain drugs, infections, and foods like fava beans.

Management and Treatment

While there is currently no cure for G6PD deficiency, management strategies focus on avoiding triggers of hemolytic crises and providing supportive care during acute episodes of anemia. In severe cases, blood transfusions may be necessary to alleviate symptoms and complications.

Raising Awareness and Promoting Understanding

As we delve deeper into the complexities of human genetics, it becomes increasingly important to raise awareness about conditions like G6PD deficiency. By understanding its global impact, historical context, and implications for health, we can better support affected individuals and work towards improved management and treatment strategies.

Conclusion

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is not just a genetic condition; it's a global concern with far-reaching implications. From its historical discovery to its intriguing connection with malaria, G6PD deficiency continues to captivate researchers and healthcare professionals alike. By shedding light on this condition, we can pave the way for greater understanding, support, and ultimately, improved outcomes for those affected.

As we step into the month of January, we collectively observe Thyroid Awareness Month – a dedicated time to shed light on the pivotal role played by the thyroid in our overall health and to raise awareness about the various disorders that can impact it. In India alone, studies estimate that approximately 42 million people are diagnosed with thyroid diseases, underscoring the significance of understanding and prioritizing thyroid health.

Unraveling the Thyroid's Role

The thyroid, resembling a small butterfly-shaped gland in the neck, orchestrates critical bodily functions such as metabolism, energy levels, and hormone balance. Conditions like hypothyroidism and hyperthyroidism, characterized by imbalances in hormone production, are particularly prevalent, affecting millions.

Hypothyroidism manifests as inadequate hormone production, resulting in symptoms like fatigue, weight gain, and sensitivity to cold temperatures. On the other hand, hyperthyroidism involves the excessive production of thyroid hormones, leading to an overactive metabolism and symptoms such as weight loss, increased heart rate, irritability, and heat intolerance.

Thyroid Awareness Month: A Call to Action

This month serves as a reminder to prioritize thyroid health. Here are actionable steps you can take:

1. Recognize Symptoms: Familiarize yourself with signs such as unexplained weight changes, fatigue, sensitivity to cold, muscle weakness, and irregular bowel movements.
2. Balanced Diet: Incorporate iodine-rich foods like seafood, dairy products, and iodized salt, along with selenium-rich foods such as Brazil nuts and sunflower seeds.
3. Physical Activity: Regular exercise supports metabolic health and may positively impact thyroid function. Stress reduction techniques like meditation and yoga can also contribute.
4. Regular Check-ups: Schedule routine health check-ups and opt for a Thyroid Profile blood test, including T3, T4, and TSH levels, to assess thyroid function.

Empowering with Genetic Insights

Early diagnosis remains pivotal, and the MyDNA Geneproactive test offers genetic analysis of Single Nucleotide Polymorphisms (SNPs) related to hypothyroidism. SNPs are tiny changes in the DNA code, making each person unique. Armed with this knowledge, individuals can collaborate with genetic counselors to implement personalized lifestyle changes and proactive healthcare measures.

By embracing personalized adjustments, individuals can potentially mitigate the impact of genetic predispositions, optimizing overall thyroid health. Unveiling this genetic information empowers individuals to gain a deeper understanding of their risk factors and take proactive steps toward preventive healthcare.

In navigating the intricate landscape of thyroid health, awareness and personalized care emerge as our compass. Let this Thyroid Awareness Month be a catalyst for informed choices, fostering a journey towards holistic well-being and a brighter, healthier future.

In the ever-evolving landscape of health and wellness, dietary advice seems to be everywhere. From trendy diets to well-meaning recommendations, the idea of a one-size-fits-all diet has permeated popular culture. However, the more we delve into the intricate world of genetics, the clearer it becomes that our individual genetic makeup plays a significant role in how our bodies respond to different foods. In this blog post, we will explore the concept of unique genetics and its impact on diet, debunking the myth that one universal diet can cater to the diverse needs of every individual.

Understanding Genetic Diversity:

The human genome is a marvel of complexity, comprising a vast array of genes that influence our traits, behaviors, and, importantly, our metabolism. Genetic variations are inherent, contributing to the diversity observed in how individuals process and utilize nutrients. For example, some people may metabolize carbohydrates more efficiently, while others thrive on a higher fat intake. Recognizing and embracing this diversity is key to tailoring diets that truly work for each person.

The Fallacy of One-Size-Fits-All Diets:

Despite the popularity of diets proclaiming universal benefits, such as ketogenic, paleolithic, or vegetarian, it's crucial to acknowledge that what works wonders for one person may not yield the same results for another. Genetic factors such as metabolism, insulin sensitivity, and nutrient absorption can vary significantly among individuals. This means that adhering strictly to a particular dietary regimen without considering individual genetic nuances may lead to suboptimal results or even health issues.

The Role of Nutrigenomics:

Nutrigenomics, the study of how individual genetic variations influence responses to nutrients, has shed light on the intricate relationship between genetics and diet. Through advancements in genetic testing, individuals can gain insights into their unique genetic makeup and how it may impact their nutritional needs. Understanding one's genetic predispositions allows for a more personalized approach to diet and lifestyle choices.

Tailoring Diets to Genetic Profiles:

Rather than subscribing to generic diet plans, an emerging trend in the health and wellness industry involves tailoring nutrition advice to individual genetic profiles. For instance, a person with a genetic predisposition for lactose intolerance might find a lactose-free diet more suitable, while someone with a high metabolic rate may benefit from a balanced macronutrient intake. Personalized nutrition takes into account factors such as food sensitivities, nutrient requirements, and metabolic tendencies.

In the pursuit of optimal health and wellness, recognizing and celebrating the uniqueness of our genetics is paramount. The myth of the one-size-fits-all diet is gradually giving way to a more personalized and nuanced approach to nutrition. Embracing the knowledge gleaned from nutrigenomics allows individuals to make informed dietary choices that align with their genetic predispositions, promoting not only better health but also a deeper understanding of the intricate interplay between genes and nutrition. As we navigate the ever-expanding realm of personalized health, the message is clear: our genes shape our dietary needs, and acknowledging this diversity is the key to unlocking our individual paths to well-being.

As winter blankets the world in a serene layer of frost, our focus naturally shifts towards staying warm and healthy. While the season encourages cozy blankets and warm beverages, did you know that your genetic makeup may also play a role in how your body responds to the winter chill? In this blog, we'll explore the intriguing connection between winter health and genetics.

People genetically predisposed to have high LDL cholesterol are at an increased risk for coronary heart disease even if their cholesterol levels are modestly elevated, as per the recent study published in Circulation.

Familial hypercholesterolemia, a genetic disorder causes elevated LDL (sometimes called "bad") cholesterol from birth and often leads to coronary heart disease at a young age.

Familial hypercholesterolemia affects around 1 in 250 people in the U.S., as per the Centers for Disease Control and Prevention.

In the study, the study group analyzed data from more than 21,000 participants with no existing coronary heart disease who underwent whole genome sequencing as part of six previously conducted population-based cardiovascular studies. Investigators noted any variations in genes typically associated with familial hypercholesterolemia, as well as each person's LDL cholesterol levels and other risk factors, including smoking status and BMI.

After following up with the participants for about 20 years later, the study group found that people with high LDL cholesterol and the associated familial hypercholesterolemia genetic variants were nearly four times more likely to have coronary heart disease than those without the variants, according to the study.

Additionally, the presence of familial hypercholesterolemia genetic variations was associated with a higher risk of coronary heart disease, even when LDL cholesterol levels were only modestly elevated.

Pooling together genetic and cholesterol data, and then outcomes data from these six population-based studies, high cholesterol is worse than low cholesterol, but high cholesterol that's related to one of these single-gene disorders is particularly risky and even riskier than the polygenic variety.

"These findings will beg the question, 'Does this mean we need to do genetic testing in everybody who has high cholesterol levels?' I think it suggests that we might want to do more of it, and particularly in familial settings," the author said.

"If we identify one person, we want to do what we call cascade screening: Find other people in the family who might be affected by this so that we understand all of the risk in the family. But in general, the tools and the steps that we'll take to control that cholesterol will be the same regardless of whether I know they have an underlying single gene defect or not."

A study group from Melbourne, Australia conducted a Prospective study of women with invasive or high grade in situ breast cancer and unknown germline status and the same discussed at the multidisciplinary team meeting. Women were recruited to the pilot (12 June 2020 - 22 March 2021) and expansion phases (17 October 2021 - 8 November 2022) of the Mutational Assessment of newly diagnosed breast cancer using Germline and tumour genomICs (MAGIC) study to determine the feasibility of universal genetic testing of women with newly diagnosed breast cancer, to estimate the incidence of pathogenic gene variants and their impact on patient management, and to evaluate patient and clinician acceptance of universal testing.The study group identified pathogenic germline variants in 31 of 474 expanded study phase participants (6.5%), including 28 of 429 women with invasive breast cancer (6.5%).

18 of the 31 did not meet current genetic testing eligibility guidelines (probability of a germline pathogenic variant ≥ 10%, based on CanRisk, or Manchester score ≥ 15). In 24 of 31 women clinical management was changed for after identification of a pathogenic variant. Further, 68 women who underwent genetic testing outside the study, 44 of 542 women carried pathogenic variants (8.1%).

“Acceptance of universal testing was high among both patients (90 of 103, 87%) and clinicians; no decision regret or adverse impact on psychological distress or cancer-specific worry were reported as per the investigators”

Finally, universal genetic testing following the diagnosis of breast cancer detects clinically significant germline pathogenic variants that might otherwise be missed because of testing guidelines. Routine testing and reporting of pathogenic variants is feasible and acceptable for both patients and clinicians.
