Apolipoprotein B Associated with thrombophilia ?5 answersApolipoprotein B (ApoB) is not directly associated with thrombophilia, but it plays a crucial role in lipid metabolism. Studies have shown that ApoB is a highly polymorphic protein, with different forms and alleles being distinguished using specific markers. Thrombophilia, a condition predisposing individuals to excessive blood clotting, is often linked to genetic variations in genes encoding factors of the hemostatic system. While there is ongoing research on the relationship between thrombophilia and adverse pregnancy outcomes, including the consideration of genetic and acquired markers for thrombophilia in cases of preeclampsia, abruptio placenta, and fetal loss, ApoB itself is not a direct genetic risk factor for thrombophilia.
Is HIGM x-linked or autosomal recessive?3 answersHyper IgM syndrome (HIGM) can be inherited in both X-linked and autosomal recessive fashion. The X-linked form is the most common, caused by mutations in the CD40L gene. The autosomal recessive form can be caused by mutations in the AICDA gene.
What are the examples of different inherited metabolic disorders?5 answersInherited metabolic disorders encompass a wide range of conditions that affect the body's processing and distribution of macronutrients. Examples of these disorders include metabolic myopathies, which are characterized by a deficiency or dysfunction of essential metabolites or fuels for muscle contraction. These myopathies can be further classified into glycogenosis, disorders of lipid metabolism, and mitochondrial myopathies. Other examples of inherited metabolic disorders include organic acidopathies, amino acidopathies, fatty acid disorders, and lysosomal storage diseases. These disorders can result from enzyme deficiencies or defects in the biosynthesis or degradation of glycoconjugates. Symptoms of inherited metabolic disorders can vary widely, but may include muscle weakness, myalgia, rhabdomyolysis, lethargy, weight loss, jaundice, seizures, and other multisystemic manifestations. Early detection and accurate diagnosis of these disorders are crucial for proper treatment and better outcomes.
How inherited is homosexuality?5 answersHomosexuality has a substantial heritability in both sexes, as indicated by pedigree and twin studies. However, the concordance between identical twins is low, and molecular studies have not found associated DNA markers. Genetic factors have been suggested as a possible cause of homosexuality, with evidence from twin and family studies supporting the idea that homosexuality runs in families. These studies indicate that genes may account for at least half of the variance in sexual orientation. It is proposed that homosexuality is a polygenetic trait influenced by multiple genes that shift male brain development in the female direction. The presence of hereditary factors in homosexuality could be microforms of inherited endocrine diseases or equivalents of inherited psychiatric diseases. The survival of a human predisposition for homosexuality may be explained by a balanced polymorphism that provides a high degree of variability among offspring personalities.
Does thrombophilia affect a person's ability to engage in physical activity?5 answersThrombophilia can affect a person's ability to engage in physical activity. Physical activity is increasingly advocated for patients with haemophilia, but less than 50% of people with haemophilia actually engage in physical activity or sport. While regular exercise has been proposed to decrease the risk of developing thrombosis, there are inconsistent data on its effects, with reports of both increased and decreased thrombotic risk across different subject cohorts. Additionally, intensive training can expose athletes to potentially thrombogenic risk factors, such as heat stress, dehydration, blood vessel injury, and inflammation. The extent to which these risk factors increase the chances of blood clot precipitation in certain participants warrants attention. Therefore, individuals with thrombophilia may need to consider their condition and potential risks before engaging in physical activity.
What is the relationship between genetics and homosexuality?4 answersGenetic influences may play a role in the development of homosexuality, but psychological and social factors also play a major role. The role of genetics in homosexuality has been a hotly debated topic, with the popularity of environmental influences overshadowing genetic factors. The genetic locus Xq28 has been identified as one of the most important genetic factors related to sexual orientation, although subsequent studies have weakened the link between Xq28 and homosexuality. Another study suggests that genes may influence male sexual orientation, but the evidence for a genetic contribution to female homosexuality is less well developed. However, all studies on the genetic basis of sexual orientation have failed to meet the necessary criteria for valid genetic analysis. Molecular research on homosexuality faces challenges due to societal stigmatization, but evidence suggests a genetic contribution to sexual orientation. Scientific discoveries do not resolve moral dilemmas, and ethical discussions are needed to prevent possible abuses.
