Invitae | RCV000698982 | SCV000827673 | uncertain significance | Xanthinuria type II | 2022-08-09 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 121 of the XDH protein (p.Val121Ile). This variant is present in population databases (rs751332444, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with XDH-related conditions. ClinVar contains an entry for this variant (Variation ID: 576475). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. |
