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]

The c.1954G>A (p.E652K) 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 1954, causing the glutamic acid (E) at amino acid position 652 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
