Unique ID: D020143
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D020143
Scope Note: A group of recessively inherited diseases characterized by the intralysosomal accumulation of G(M2) GANGLIOSIDE in the neuronal cells. Subtypes include mutations of enzymes in the BETA-N-ACETYLHEXOSAMINIDASES system or G(M2) ACTIVATOR PROTEIN leading to disruption of normal degradation of GANGLIOSIDES, a subclass of ACIDIC GLYCOSPHINGOLIPIDS.
Entry Term(s): G(M2) Gangliosidoses; GM2 Gangliosidosis; Gangliosidoses GM2
