Genes affected

GPRASP2 (HGNC:25169): (G protein-coupled receptor associated sorting protein 2) The protein encoded by this gene is a member of a family that regulates the activity of G protein-coupled receptors (GPCRs). The encoded protein has been shown to be capable of interacting with several GPCRs, including the M1 muscarinic acetylcholine receptor and the calcitonin receptor. Several transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, May 2010]

GPRASP2 links:

ARMCX5-GPRASP2 (HGNC:42000): (ARMCX5-GPRASP2 readthrough) This locus represents naturally occurring readthrough transcription among the adjacent armadillo repeat containing, X-linked 5 (ARMCX5), G protein-coupled receptor associated sorting proteins 1 and 2 (GPRASP1 and GPRASP2), basic helix-loop-helix family member b9 (BHLHB9), and long intergenic non-protein coding RNA 630 (LINC00630) genes on chromosome X. Transcripts may make use of multiple alternative promoters and polyadenylation signals in this region. Readthrough transcripts may produce proteins identical to the proteins encoded by GPRASP2 or BHLHB9. [provided by RefSeq, Apr 2017]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.287C>T (p.A96V) alteration is located in exon 5 (coding exon 1) of the GPRASP2 gene. This alteration results from a C to T substitution at nucleotide position 287, causing the alanine (A) at amino acid position 96 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
