Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_182947.4(ARHGEF25):​c.1517A>T​(p.Gln506Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q506R) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ARHGEF25 NM_182947.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.364

Genes affected

ARHGEF25 (HGNC:30275): (Rho guanine nucleotide exchange factor 25) Rho GTPases alternate between an inactive GDP-bound state and an active GTP-bound state, and GEFs facilitate GDP/GTP exchange. This gene encodes a guanine nucleotide exchange factor (GEF) which interacts with Rho GTPases involved in contraction of vascular smooth muscles, regulation of responses to angiotensin II and lens cell differentiation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

ENSG00000287908 (HGNC:):
