Genes affected

ARMCX5 (HGNC:25772): (armadillo repeat containing X-linked 5)

ARMCX5 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]

The c.404G>T (p.R135M) alteration is located in exon 6 (coding exon 1) of the ARMCX5 gene. This alteration results from a G to T substitution at nucleotide position 404, causing the arginine (R) at amino acid position 135 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
