MGI Phenotype Strain: 3531502
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Aging mice homozygous for a knock-out allele display motor dysfunction and abnormal social interaction, hematologic anomalies including acanthocytosis, selective atrophy of the striatum with significant apoptosis and gliosis, and reduced homovanillic acid levels in midbrain.

Protein Function and Prediction

Vps13a encodes chorein (alternatively, CHAC), a protein proposed to function in cytoskeleton and intracellular protein sorting including the regulation of dense-core vesicle exocytosis (1-5).

Expression/Localization

One study observed the Vps13a transcript in heart, skeletal muscle, and kidney (6). Chorein is highly expressed in testis, kidney, spleen, and brain. In wild-type mouse brain, chorein is predominantly localized to microsomal and synaptosomal fractions, the neuronal perinuclear region, cytoplasm, and fibers (7).

Background

Mutations in VPS13A are linked to choreoacanthocytosis [OMIM: #200150; (1;6)], a disorder characterized by progressive neurodegeneration and red cell acanthocytosis, with onset in the third to fifth decade of life (8).

 

Vps13atm1Asan/tm1Asan; MGI:3531502

involves: 129S/SvEv

Aging mice homozygous for a knock-out allele display motor dysfunction and abnormal social interaction, hematologic anomalies including acanthocytosis, selective atrophy of the striatum with significant apoptosis and gliosis, and reduced homovanillic acid levels in midbrain (9).
