Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_018287.7(ARHGAP12):c.1373C>T(p.Ala458Val) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000379 in 1,609,272 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/23 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A458S) has been classified as Uncertain significance.

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]

Ambry Genetics

Apr 26, 2023

The c.1373C>T (p.A458V) alteration is located in exon 9 (coding exon 7) of the ARHGAP12 gene. This alteration results from a C to T substitution at nucleotide position 1373, causing the alanine (A) at amino acid position 458 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
