Tay-Sachs disease, or TSD for short, is a lysosomal storage disorder caused by a mutation in a gene on chromosome 15, which codes for a lysosomal enzyme called beta-hexosaminidase A, or HEX-A for short.. This enzyme normally breaks down a lipid called GM2 ganglioside. GM2 is found mainly in neurons, so without HEX-A, it accumulates inside lysosomes تعريف باللغة الإنكليزية: Tay Sachs Disease. معاني أخرى ل TSD إلى جانبمرض تاي ساكس ، يحتويTSD علي معاني أخرى. وهي مدرجه علي اليسار أدناه. يرجى التمرير لأسفل وانقر لرؤية كل واحد منهم. لجميع معانيTSD ، الرجاء.

Introduction to Tay-Sachs Disease. Tay-Sachs disease is an autosomal recessive disease that is a member of a family of disorders identified as the G M2 gangliosidoses. The G M2 gangliosidotic diseases are severe psycho-motor developmental disorders caused by the inability to properly degrade membrane associated gangliosides of the G M2 family (see Figure below and the Sphingolipid and Ceramide. Tay-Sachs disease is a genetic disorder that affects the brain's nerve cells. Individuals who have this disorder lacks a type of protein that is needed to break down fatty substances in the brain. Without this protein, fatty substances accumulate in the brain to toxic levels, which affect the normal functioning of the nerve cells Tay-Sachs is an inherited disease that only occurs when both parents carry a Tay-Sachs gene and each parent transmits the defective gene to their child. A child who inherits two Tay-Sachs genes (one from each parent) produces no functional Hex-A enzyme and is certain to develop Tay-Sachs disease Tay-Sachs disease is caused by two genetic mutations. This happens when the instructions found in cells become scrambled in some way, causing one or more processes of the body to not work properly. In Tay-Sachs disease, a genetic mutation in the HEXA gene results in the body not producing an enzyme called Hexosaminidase-A (Hex-A)

'Tay-Sachs disease occurs when the body lacks hexosaminidase A, a protein that helps break down a chemical found in nerve tissue called gangliosides.'
