RCV001328230 | SCV001449473 | likely pathogenic | Autosomal dominant medullary cystic kidney disease with or without hyperuricemia | 2018-09-19 | no assertion criteria provided | clinical testing | This individual is heterozygous for the c.411C>G variant in the UMOD gene which results in an amino acid substitution of cystine to tryptophan at residue 137, p.(Cys137Trp). This variant has not been reported in any population databases (i.e. gnomAD, ExAC, ESP or dbSNP) and to our knowledge, has not been previously reported in the literature or any disease specific databases. In silico analysis of pathogenicity (through Alamut Visual v2.8.1) using PolyPhen2, SIFT and MutationTaster suggest that this variant is likely to be pathogenic. p.(Cys137Trp) alters a conserved cysteine residue in an EGF like domain and likely leads to protein misfolding, either by disrupting a native disulfide bond or by destabilising protein structure (Devuyst et al 2017 Nature reviews. Nephrology 13 (9):525). This variant is considered to be likely pathogenic according to the ACMG guidelines. |
