Invitae RCV000648513 SCV000770333 uncertain significance Epidermolysa bullosa simplex and limb girdle muscular dystrophy; Epidermolysis bullosa simplex, Ogna type; Epidermolysis bullosa simplex with pyloric atresia; Limb-girdle muscular dystrophy, type 2Q; Epidermolysis bullosa simplex with nail dystrophy 2018-01-04 criteria provided, single submitter clinical testing This sequence change replaces arginine with tryptophan at codon 1588 of the PLEC protein (p.Arg1588Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs782648800, ExAC 0.02%). This variant has not been reported in the literature in individuals with PLEC-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
