RCV002795977 | SCV003200758 | 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 | 2022-06-14 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with PLEC-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1770 of the PLEC protein (p.Ala1770Val). |
Ambry Genetics | RCV003167788 | SCV003910149 | uncertain significance | Inborn genetic diseases | 2023-03-14 | criteria provided, single submitter | clinical testing | The c.5309C>T (p.A1770V) alteration is located in exon 32 (coding exon 31) of the PLEC gene. This alteration results from a C to T substitution at nucleotide position 5309, causing the alanine (A) at amino acid position 1770 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
