Genes affected
ARHGEF2 (HGNC:682): (Rho/Rac guanine nucleotide exchange factor 2) 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. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Jun 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2022The c.1837G>A (p.G613R) alteration is located in exon 15 (coding exon 15) of the ARHGEF2 gene. This alteration results from a G to A substitution at nucleotide position 1837, causing the glycine (G) at amino acid position 613 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
