Relevance to Autism
This gene has been associated with syndromic autism, where a subpopulation of individuals with a given syndrome develop autism. In particular, rare mutations of the VPS13B gene have been identified with Cohen syndrome (Kolehmainen et al., 2003).
Molecular Function
This gene encodes a potential transmembrane protein that may function in vesicle-mediated transport and sorting of proteins within the cell. This protein may play a role in the development and the function of the eye, hematological system, and central nervous system. Mutations in this gene have been associated with Cohen syndrome. Multiple splice variants encoding distinct isoforms have been identified for this gene.
