Genes affected

ARHGEF15 (HGNC:15590): (Rho guanine nucleotide exchange factor 15) Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein-coupled receptors. This gene encodes a protein that functions as a specific guanine nucleotide exchange factor for RhoA. It also interacts with ephrin A4 in vascular smooth muscle cells. Two alternatively spliced transcripts variants that encode the same protein have been found for this gene. [provided by RefSeq, Aug 2010]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in ARHGEF15 cause disease. Therefore, this variant has been classified as a Variant of Uncertain Significance. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a ARHGEF15-related disease. This sequence change deletes 1 nucleotide from exon 6 of the ARHGEF15 mRNA (c.1102delG), causing a frameshift at codon 368. This creates a premature translational stop signal (p.Val368Trpfs*59) and is expected to result in an absent or disrupted protein product. -
