Genes affected
VPS13A (HGNC:1908): (vacuolar protein sorting 13 homolog A) The protein encoded by this gene may control steps in the cycling of proteins through the trans-Golgi network to endosomes, lysosomes and the plasma membrane. Mutations in this gene cause the autosomal recessive disorder, chorea-acanthocytosis. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]
VPS13A-AS1 (HGNC:44167): (VPS13A antisense RNA 1)
