RCV002914207 | SCV003257443 | uncertain significance | Klippel-Feil syndrome 1, autosomal dominant; Isolated microphthalmia 4; Microphthalmia, isolated, with coloboma 6; Leber congenital amaurosis 17 | 2022-09-20 | criteria provided, single submitter | clinical testing | 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 tolerated. This variant has not been reported in the literature in individuals affected with GDF6-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 239 of the GDF6 protein (p.Glu239Lys). |
