Description

This sequence change creates a premature translational stop signal (p.Thr364Alafs*77) in the IDUA gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in IDUA are known to be pathogenic (PMID: 11735025, 21480867). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with IDUA-related conditions. For these reasons, this variant has been classified as Pathogenic.
