Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 25, 2018 | 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 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 CCDC78-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with phenylalanine at codon 139 of the CCDC78 protein (p.Ser139Phe). The serine residue is moderately conserved and there is a large physicochemical difference between serine and phenylalanine. - |
