ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 7 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 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.8118 (below the threshold of 3.09). Trascript score misZ: 0.037837 (below the threshold of 3.09).

PP3

MetaRNN computational evidence supports a deleterious effect, 0.966
