Genes and associated diseases
Description
⠀⠀⠀⠀Although hundreds of congenital metabolic disorders have been described to date, most of these are rare. However, taken together, metabolic disorders account for a significant proportion of morbidity and mortality from genetic disorders. According to conservative studies, the incidence of metabolic disorders is approximately 1 in every 2500 births, comprising 10% of all monogenic disorders in children. Moreover, different alleles of genes encoding enzymes can alter the risk factor associated with many common diseases such as diabetes, heart disease, stroke, and cancer.


⠀⠀⠀⠀ Organic acid metabolism disorders are considered rare hereditary diseases. Along with the possible pathogenic genetic variants (mutations) that cause them, however, they remain poorly studied. The use of high-throughput sequencing allows the identification of already known and novel variants in all coding regions of linked genes. Detection of mutant variants in a child or the positive carrier status of parents allows genetic counseling for further diagnostics or reproductive manipulations.
