Genes affected

ARHGAP12 (HGNC:16348): (Rho GTPase activating protein 12) This gene encodes a member of a large family of proteins that activate Rho-type guanosine triphosphate (GTP) metabolizing enzymes. The encoded protein may be involved in suppressing tumor formation by regulating cell invasion and adhesion. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

ARHGAP12 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.31576106).

The c.2455A>G (p.T819A) alteration is located in exon 20 (coding exon 18) of the ARHGAP12 gene. This alteration results from a A to G substitution at nucleotide position 2455, causing the threonine (T) at amino acid position 819 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
