Genes affected

ARHGEF12 (HGNC:14193): (Rho guanine nucleotide exchange factor 12) Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli working through G protein-coupled receptors. The encoded protein may form a complex with G proteins and stimulate Rho-dependent signals. This protein has been observed to form a myeloid/lymphoid fusion partner in acute myeloid leukemia. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.951

The c.1141C>T (p.R381C) alteration is located in exon 14 (coding exon 14) of the ARHGEF12 gene. This alteration results from a C to T substitution at nucleotide position 1141, causing the arginine (R) at amino acid position 381 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
