RCV000493669 | SCV000581765 | uncertain significance | not provided | 2017-05-01 | criteria provided, single submitter | clinical testing | The R3102W variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R3102W variant is observed in 4/8340 (0.05%) alleles from individuals of East Asian background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). This variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved in mammals; however, missense variants in nearby residues have not been reported in the Human Gene Mutation Database in association with PLEC-related disorders (Stenson et al., 2014). In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. |

RCV000550224 | SCV000650466 | 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 | 2023-04-24 | criteria provided, single submitter | clinical testing | 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 429245). This variant has not been reported in the literature in individuals affected with PLEC-related conditions. This variant is present in population databases (rs376638828, gnomAD 0.08%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 3102 of the PLEC protein (p.Arg3102Trp). |
Ambry Genetics | RCV002524014 | SCV003685410 | uncertain significance | Inborn genetic diseases | 2022-02-04 | criteria provided, single submitter | clinical testing | The c.9304C>T (p.R3102W) alteration is located in exon 33 (coding exon 32) of the PLEC gene. This alteration results from a C to T substitution at nucleotide position 9304, causing the arginine (R) at amino acid position 3102 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
