Genes affected

ZNF408 (HGNC:20041): (zinc finger protein 408) The protein encoded by this gene contains ten tandem zinc fingers and an N-terminal SET domain, so it is likely a DNA binding protein that interacts with other proteins. In adults, the encoded protein is expressed most highly in retina. Consequently, defects in this gene have been associated with familial exudative vitreoretinopathy (FEVR) and retinitis pigmentosa (RP). [provided by RefSeq, Dec 2016]

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 541 of the ZNF408 protein (p.Arg541Cys). This variant is present in population databases (rs781192528, gnomAD 0.009%). This missense change has been observed in individuals with retinitis pigmentosa (PMID: 25882705; internal data). ClinVar contains an entry for this variant (Variation ID: 204317). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects ZNF408 function (PMID: 25882705). For these reasons, this variant has been classified as Pathogenic. -
