Invitae RCV001233899 SCV001406514 likely pathogenic Treacher Collins syndrome 1 2019-10-04 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) affected with Treacher Collins syndrome (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with glycine at codon 30 of the TCOF1 protein (p.Val30Gly). The valine residue is highly conserved and there is a moderate physicochemical difference between valine and glycine.
