ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 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 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: -0.15261 (below the threshold of 3.09). Trascript score misZ: -0.33228 (below the threshold of 3.09). GenCC associations: The gene is linked to Garg-Mishra progeroid syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.776
