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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.382A>G (p.T128A) alteration is located in exon 4 (coding exon 2) of the ARHGEF4 gene. This alteration results from a A to G substitution at nucleotide position 382, causing the threonine (T) at amino acid position 128 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
