Description

The variant is not observed in the gnomAD v2.1.1 dataset. Frameshift: predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant is shared with the similarly affected father and the sibling (3billion dataset). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline.
