Description

The variant is not observed in the gnomAD v2.1.1 dataset. The variant in the canonical splice site is predicted to alter splicing, resulting in a loss or disruption of normal protein function. Multiple pathogenic loss-of-function variants are reported downstream of the variant. The variant has been reported at least twice as pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000375810). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline.
