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]

ClinVar contains an entry for this variant (Variation ID: 530538). This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 12 of the ARHGEF15 protein (p.Pro12Ala). This variant is present in population databases (rs150480540, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with ARHGEF15-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
