Description

The variant is not observed in the gnomAD v2.1.1 dataset. This variant was predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline.
