Genes affected

ARHGEF4 (HGNC:684): (Rho guanine nucleotide exchange factor 4) Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The protein encoded by this gene may form complex with G proteins and stimulate Rho-dependent signals. Multiple alternatively spliced transcript variants encoding different isoforms have been found, but the full-length nature of some variants has not been determined. [provided by RefSeq, Jun 2013]

Apr 19, 2023

The c.185C>T (p.S62L) alteration is located in exon 3 (coding exon 1) of the ARHGEF4 gene. This alteration results from a C to T substitution at nucleotide position 185, causing the serine (S) at amino acid position 62 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
