| Invitae | RCV002028313 | SCV002278204 | uncertain significance | Asphyxiating thoracic dystrophy 5; Senior-Loken syndrome 8 | 2021-09-24 | criteria provided, single submitter | clinical testing | This sequence change replaces serine with glycine at codon 1131 of the WDR19 protein (p.Ser1131Gly). The serine residue is highly conserved and there is a small physicochemical difference between serine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with WDR19-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glycine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. |
