Description

Frameshift: 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 not observed in the gnomAD v2.1.1 dataset (PM2). Patient's phenotype is considered compatible with Krabbe disease (3billion dataset, PP4). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.
