Genes and associated diseases
Description
⠀⠀⠀⠀Lysosomal storage diseases (LSDs) are hereditary metabolic diseases characterised by the abnormal accumulation of various toxic substances in the cells of the body as a result of enzyme deficiency. Comprising about 50 already identified diseases, LSDs can affect various parts of the body, including the skeleton, skin, heart and central nervous system. The use of high-throughput sequencing allows the identification of already known and novel genetic variants (mutations) 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.
