Genes affected
AP1S3 (HGNC:18971): (adaptor related protein complex 1 subunit sigma 3) This gene encodes a member of the adaptor-related protein complex 1, sigma subunit genes. The encoded protein is a component of adaptor protein complex 1 (AP-1), one of the AP complexes involved in claathrin-mediated vesicular transport from the Golgi or endosomes. Disruption of the pathway for display of HIV-1 antigens, which prevents recognition of the virus by cytotoxic T cells, has been shown to involve the AP-1 complex (PMID: 15569716). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2014]

The c.256C>T (p.R86C) alteration is located in exon 3 (coding exon 3) of the AP1S3 gene. This alteration results from a C to T substitution at nucleotide position 256, causing the arginine (R) at amino acid position 86 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
