Description

Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with ERCC4-related conditions. This variant is present in population databases (rs774900622, ExAC 0.006%). This sequence change replaces glycine with valine at codon 703 of the ERCC4 protein (p.Gly703Val). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and valine.
