Ambry Genetics | RCV003193233 | SCV003882726 | uncertain significance | Inborn genetic diseases | 2023-01-11 | criteria provided, single submitter | clinical testing | The c.4472C>A (p.T1491N) alteration is located in exon 32 (coding exon 31) of the PLEC gene. This alteration results from a C to A substitution at nucleotide position 4472, causing the threonine (T) at amino acid position 1491 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV003779681 | SCV004605744 | 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 | 2023-10-17 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 1491 of the PLEC protein (p.Thr1491Asn). This variant is present in population databases (no rsID available, gnomAD 0.002%). 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: 2475767). 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) performed at Invitae indicates that this missense variant is not expected to disrupt 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. |
