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 GeneticsFeb 14, 2023The c.1949G>A (p.R650H) 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 1949, causing the arginine (R) at amino acid position 650 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
