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.
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.
When beta-hexosaminidase is no longer functioning properly, the lipids accumulate in the nervous tissue of the brain and cause problems. Gangliosides are made and biodegraded rapidly in early life as the brain develops. Except in some rare, late-onset forms, the GM2 gangliosidoses are fatal. [1] All three disorders are rare in the general ...
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.

GM1-gangliosidosis is a lysosomal storage disease that can be caused by a deficiency of β-galactosidase (GLB1). Some cases of Morquio syndrome B have been shown to be due to GLP1 mutations that cause patients to have abnormal elastic fibers .
This rare type causes scar tissue to replace normal heart muscle. Stress-induced cardiomyopathy. Also known as “broken heart syndrome,” this type of cardiomyopathy is induced by emotional stress.
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle.It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart.
