Genes affected

ARHGEF1 (HGNC:681): (Rho guanine nucleotide exchange factor 1) Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The encoded protein may form complex with G proteins and stimulate Rho-dependent signals. Multiple alternatively spliced transcript variants have been found for this gene, but the full-length nature of some variants has not been defined. [provided by RefSeq, Jul 2008]

Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 21 of the ARHGEF1 protein (p.Arg21Gln). This variant is present in population databases (rs183598386, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ARHGEF1-related conditions. 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. -
