Inborn genetic diseases Uncertain:1
The c.4186A>G (p.R1396G) alteration is located in exon 21 (coding exon 20) of the ERCC6 gene. This alteration results from a A to G substitution at nucleotide position 4186, causing the arginine (R) at amino acid position 1396 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

not provided Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 1396 of the ERCC6 protein (p.Arg1396Gly). This variant is present in population databases (rs745352643, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with ERCC6-related conditions. ClinVar contains an entry for this variant (Variation ID: 190173). 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. 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. -
