ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-169764738-G-A is Pathogenic according to our data. Variant chr3-169764738-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 39291.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr3-169764738-G-A is described in Lovd as [Pathogenic].
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.16). . Strength limited to SUPPORTING due to the PP5.
