Genes affected

ARMC12 (HGNC:21099): (armadillo repeat containing 12) Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000232909 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 3 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.27213 (below the threshold of 3.09). Trascript score misZ: 1.0694 (below the threshold of 3.09).
• BP4: Computational evidence support a benign effect (MetaRNN=0.050952137).

Collection Method: clinical testing

The c.52G>A (p.V18I) alteration is located in exon 1 (coding exon 1) of the ARMC12 gene. This alteration results from a G to A substitution at nucleotide position 52, causing the valine (V) at amino acid position 18 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
