Gangliosidosis contains different types of lipid storage disorders [1] caused by the accumulation of lipids known as gangliosides. There are two distinct genetic causes of the disease. There are two distinct genetic causes of the disease.
GM2-gangliosidosis, AB variant is a rare, autosomal recessive metabolic disorder that causes progressive destruction of nerve cells in the brain and spinal cord. Mutations in the GM2A gene cause AB variant. The GM2A gene provides instructions for making a protein called the GM2 activator.
The GM1 gangliosidoses, usually shortened to GM1, are gangliosidoses caused by mutation in the GLB1 gene resulting in a deficiency of beta-galactosidase.The deficiency causes abnormal storage of acidic lipid materials in cells of the central and peripheral nervous systems, but particularly in the nerve cells, resulting in progressive neurodegeneration.
Heart disease is a type of cardiovascular disease that affects the heart’s structure and function. Several different heart conditions fall under the umbrella term for heart disease.
Mutations in genes coding for these enzymes leads to the accumulation of partially broken down gangliosides in lysosomes, which results in a group of diseases called gangliosidosis. For example, the fatal Tay–Sachs disease arises as a genetic defect which leads to no functional hexosaminidase A produced, causing GM2 to accumulate in lysosomes.
GM 2 gangliosidosis refers to several similar genetic disorders: Tay–Sachs disease; Sandhoff disease; GM2-gangliosidosis, AB variant
GM1 gangliosidosis are inherited disorders that progressively destroy neurons in the brain and spinal cord as GM1 accumulates. Without treatment, this results in developmental decline and muscle weakness, eventually leading to severe retardation and death.
Sphingolipidoses are a class of lipid storage disorders or degenerative storage disorders caused by deficiency of an enzyme that is required for the catabolism of lipids that contain ceramide, [1] also relating to sphingolipid metabolism.
