ACMG classification

Classification was made for transcript

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 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).

BP4

Computational evidence support a benign effect (MetaRNN=0.03054896).
