ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. 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=0.08568695).

Collection Method:clinical testing

The c.43C>T (p.R15C) alteration is located in exon 1 (coding exon 1) of the ARMC12 gene. This alteration results from a C to T substitution at nucleotide position 43, causing the arginine (R) at amino acid position 15 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
