Web8 dec. 2024 · How is Tay Sachs disease inherited from parents? Autosomal recessive inheritance means that a person receives a nonworking copy of the HEXA gene from both parents. The parents have one working copy of the gene and one nonworking copy; they are carriers for Tay-Sachs disease. Carriers do not develop symptoms of the disorder. WebTay–Sachs disease is an autosomal recessive, progressive neurodegenerative disorder that begins in infancy. It is caused by a mutation in the alpha subunit of the hexosaminidase A gene (HEXA) that results in the accumulation of ganglioside GM2 in nervous tissue leading to cell damage.

WebTay-Sachs disease is a progressive, degenerative disease of the brain and central nervous system. It occurs when certain fats accumulate in the brain and nerve cells, causing damage to the cells and eventually causing the cells to die. The loss of healthy nerve cells results in symptoms affecting the sufferer’s motor and cognitive functions. WebTay-Sachs disease is caused by a genetic mutation in the HEXA gene. This mutation affects the production of an enzyme called Hexosaminidase-A (Hex-A). Enzymes are proteins that the body uses for chemical reactions. The Hex-A enzyme plays a vital role in helping to remove a fatty substance called ganglioside from nerve cells.
