Description

The variant is not observed in the gnomAD v2.1.1 dataset. Predicted Consequence/Location: Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through protein truncation. The predicted truncated protein may be shortened by more than 10%. Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline.
