Labcorp Genetics (formerly Invitae), Labcorp RCV000701355 SCV000830154 uncertain significance Rett syndrome, congenital variant 2017-10-07 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. A different missense substitution at this codon (p.Ser185Cys) has been determined to be likely pathogenic (PMID: 28554332). This suggests that the serine residue is critical for FOXG1 protein function and that other missense substitutions at this position may also be pathogenic. 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: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with FOXG1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with threonine at codon 185 of the FOXG1 protein (p.Ser185Thr). The serine residue is highly conserved and there is a small physicochemical difference between serine and threonine.
