Labcorp Genetics (formerly Invitae), Labcorp RCV000535817 SCV000650204 uncertain significance Epidermolysis bullosa simplex 5B, with muscular dystrophy; Epidermolysis bullosa simplex, Ogna type; Epidermolysis bullosa simplex 5C, with pyloric atresia; Autosomal recessive limb-girdle muscular dystrophy type 2Q; Epidermolysis bullosa simplex with nail dystrophy 2019-07-04 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function output the following: (SIFT: "Tolerated"; PolyPhen-2: "Unknown"; Align-GVGD: "Class C0"). The glutamic acid 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. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a PLEC-related disease. This sequence change replaces glycine with glutamic acid at codon 763 of the PLEC protein (p.Gly763Glu). The glycine residue is weakly conserved and there is a moderate physicochemical difference between glycine and glutamic acid.
