Genes affected

GPANK1 (HGNC:13920): (G-patch domain and ankyrin repeats 1) This gene is located in a cluster of HLA-B-associated transcripts, which is included in the human major histocompatability complex III region. This gene encodes a protein which is thought to play a role in immunity. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Nov 2010]

The c.944G>A (p.R315Q) alteration is located in exon 3 (coding exon 2) of the GPANK1 gene. This alteration results from a G to A substitution at nucleotide position 944, causing the arginine (R) at amino acid position 315 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
