Fanconi anemia Uncertain:1
This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 519 of the SLX4 protein (p.Cys519Arg). This variant is present in population databases (rs746419738, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with SLX4-related conditions. ClinVar contains an entry for this variant (Variation ID: 456290). An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
