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.2608C>T (p.P870S) alteration is located in exon 20 (coding exon 20) of the ARHGEF2 gene. This alteration results from a C to T substitution at nucleotide position 2608, causing the proline (P) at amino acid position 870 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
