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. It is not observed in the gnomAD v2.1.1 dataset. This variant has been reported to be associated with VPS33B related disorder (PMID:18853461). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.

Description

Progressive Familial Intrahepatic Cholestasis 12

For discussion of the 1-bp duplication (c.109dupG, NM_018668.4) in the VPS33B gene, causing a frameshift predicted to result in a premature termination codon (Lys504GlufsTer), that was found in compound heterozygous state in a Chinese brother (P2) and sister (P3) with isolated cholestasis (PFIC12; 610010) by Qiu et al. (2019), see 608552.0011.

Arthrogryposis, Renal Dysfunction, and Cholestasis 1

In a Chinese female infant (P4) who died at the age of 6 months with arthrogryposis, renal dysfunction, and cholestasis-1 (ARCS1; 208085), Qiu et al. (2019) identified compound heterozygosity for the c.109dupG mutation and a splice site mutation (c.403+2T-A; 608552.0013).
