Description

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 554156). This variant has not been reported in the literature in individuals affected with IDUA-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.1424_1426del, results in the deletion of 1 amino acid(s) of the IDUA protein (p.Tyr475del), but otherwise preserves the integrity of the reading frame.
