Description

This sequence change creates a premature translational stop signal (p.Tyr72*) in the IGHMBP2 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with IGHMBP2-related conditions. Loss-of-function variants in IGHMBP2 are known to be pathogenic (PMID: 14681881). For these reasons, this variant has been classified as Pathogenic.
