Labcorp Genetics (formerly Invitae), Labcorp RCV001054945 SCV001219304 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 2020-09-30 criteria provided, single submitter clinical testing This sequence change replaces alanine with glutamic acid at codon 1631 of the PLEC protein (p.Ala1631Glu). The alanine residue is moderately conserved and there is a moderate physicochemical difference between alanine and glutamic acid. 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. 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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with PLEC-related conditions. ClinVar contains an entry for this variant (Variation ID: 850716). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database.
