Genes affected

DCAF8 (HGNC:24891): (DDB1 and CUL4 associated factor 8) This gene encodes a WD repeat-containing protein that interacts with the Cul4-Ddb1 E3 ligase macromolecular complex. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2009]

This sequence change replaces threonine with isoleucine at codon 270 of the DCAF8 protein (p.Thr270Ile). The threonine residue is moderately conserved and there is a moderate physicochemical difference between threonine and isoleucine. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DCAF8-related conditions. This variant is present in population databases (rs753753498, ExAC 0.006%). -
