Labcorp Genetics (formerly Invitae), Labcorp RCV001207202 SCV001378546 likely pathogenic Ehlers-Danlos syndrome, type 4 2019-10-18 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. This sequence change replaces phenylalanine with leucine at codon 1456 of the COL3A1 protein (p.Phe1456Leu). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and leucine. 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: "Not Available"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with clinical features of Ehlers Danlos syndrome, vascular type (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).
