RCV001097204 | SCV001253463 | uncertain significance | Familial porphyria cutanea tarda | 2017-04-27 | criteria provided, single submitter | clinical testing | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. |

RCV003117750 | SCV003786825 | uncertain significance | not provided | 2024-10-02 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 128 of the UROD protein (p.Ala128Asp). This variant is present in population databases (rs141792226, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with UROD-related conditions. ClinVar contains an entry for this variant (Variation ID: 874339). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt UROD protein function with a negative predictive value of 80%. 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. |
