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.

Bipolar disorder, characterised by its distinct mood swings between mania and depression, affects 46 million globally. Bipolar disorder often emerges during adolescence and early adulthood. However, symptoms can appear much earlier, sometimes in childhood. It has long been recognized as a complex interplay between genetic predisposition and environmental factors. 

Lack of Self-Awareness:

During manic episodes, individuals may lack insight into their own behaviour. They might feel invincible, make impulsive decisions, or engage in risky activities without fully understanding the consequences.

Stigma and Misconceptions:

There's a lot of misunderstanding surrounding bipolar disorder. People often confuse it with moodiness or simply being "dramatic." This can make it difficult for individuals with the condition to seek help or feel validated.

Family History : The Intertwined Threads

Family history paints a clear picture: individuals with a close relative diagnosed with bipolar disorder have a significantly higher risk of developing the condition themselves. This suggests a strong genetic influence. However, understanding it is not as simple as a single gene mutation. Bipolar disorder is considered a polygenic condition, meaning multiple genes, each with small effects, contribute to the overall risk.

Genes on the Radar:

Genetic advancement have helped identify several genes associated with bipolar disorder, including:

• ANK3: Mutations in this gene have been linked to bipolar disorder, with possible implications for brain development and function.
• PALB2 : The specific SNP associated with bipolar disorder might alter the function of the PALB2 protein, potentially impacting these critical cellular processes. This altered function could be related to the development of bipolar disorder.
• LAMP3 : LAMP3, or lysosomal-associated membrane protein 3, plays a role in cellular processes. Research suggests it to be involved in cell death (apoptosis).
• DGKH : DGKH has also been identified as the strongest Panic Disorder associated gene. It has also been associated with altered brain activity in regions involved in mood regulation, potentially contributing to the development of bipolar disorder.

Beyond the Genes: The Environmental Trigger

While genetics provide a foundation for susceptibility, environmental factors act as triggers that can push an individual towards developing bipolar disorder. These can include:

• Stressful life events: Traumatic experiences or significant life changes can exacerbate mood imbalances.
• Substance abuse: Drug and alcohol use can worsen symptoms and potentially trigger episodes.
• Early life experiences: Childhood trauma or neglect may increase vulnerability to the disorder.

The Evolving Landscape of Genetic Research:

Understanding the genetic basis of bipolar disorder holds immense potential for the future:

• Improved Diagnosis: Genetic markers could aid in earlier identification of individuals at high risk, allowing for preventative measures or early intervention strategies.
• Personalized Treatment: Tailored treatment approaches based on an individual's genetic profile could lead to more effective management of the condition.

While the path to a definitive cure remains long, unraveling the genetics of bipolar disorder is crucial for advancements in diagnosis, treatment, and ultimately, improving the lives of those affected by this complex mental health 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.

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.
