ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.03583062 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-110799919-G-A is Pathogenic according to our data. Variant chr10-110799919-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 411658.
