Genes affected

VAPA (HGNC:12648): (VAMP associated protein A) The protein encoded by this gene is a type IV membrane protein. It is present in the plasma membrane and intracellular vesicles. It may also be associated with the cytoskeleton. This protein may function in vesicle trafficking, membrane fusion, protein complex assembly and cell motility. Alternative splicing occurs at this locus and two transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Jul 2008]

Ambry Genetics

Dec 21, 2022

The c.526A>T (p.S176C) alteration is located in exon 5 (coding exon 5) of the VAPA gene. This alteration results from a A to T substitution at nucleotide position 526, causing the serine (S) at amino acid position 176 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
