Significance: Likely pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Stop-gained (nonsense): 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 (PVS1_VS). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.0000894, PM2). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
