Labcorp Genetics (formerly Invitae), Labcorp RCV002966741 SCV003283630 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 2023-12-30 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 803 of the PLEC protein (p.Glu803Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PLEC-related conditions. ClinVar contains an entry for this variant (Variation ID: 2069926). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on PLEC protein function. 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.
PreventionGenetics, part of Exact Sciences RCV004738643 SCV005346135 uncertain significance PLEC-related disorder 2024-05-22 no assertion criteria provided clinical testing The PLEC c.2407G>C variant is predicted to result in the amino acid substitution p.Glu803Gln. To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
