The variant is not observed in the gnomAD v2.1.1 dataset. This stop-gained (nonsense) is 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. This homozygous variant has been reported to be associated with DZIP1L-related disorder (ClinVar ID: VCV000431433/ PMID: 28530676). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline. -
