RCV000354266 | SCV000387572 | benign | Emery-Dreifuss muscular dystrophy 5, autosomal dominant | 2018-01-12 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. |

RCV000354266 | SCV002211166 | uncertain significance | Emery-Dreifuss muscular dystrophy 5, autosomal dominant | 2021-09-24 | criteria provided, single submitter | clinical testing | This sequence change replaces cysteine with tyrosine at codon 5815 of the SYNE2 protein (p.Cys5815Tyr). The cysteine residue is moderately conserved and there is a large physicochemical difference between cysteine and tyrosine. This variant is present in population databases (rs143784708, ExAC 0.09%). This variant has not been reported in the literature in individuals with SYNE2-related conditions. ClinVar contains an entry for this variant (Variation ID: 313631). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The tyrosine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. |
