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]

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]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.08440393).
