ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 5.2, offset of -5, new splice context is: gtcGTaaga. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-70851211-G-A is Pathogenic according to our data. Variant chr10-70851211-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 430863.Status of the report is no_assertion_criteria_provided, 0 stars.
