Description

Canonical splice site: predicted to alter splicing and result in a loss or disruption of normal protein function through protein truncation. Multiple pathogenic variants are reported in the predicted truncated region (PVS1_VS).The variant has been reported at least twice as pathogenic/likely pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000228418). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000040, PM2_M). The variant has been reported to be in trans with a pathogenic variant (NM_206933.4:c.2187C>A) as compound heterozygous (3billion dataset, PM3_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.
