RCV001903735 | SCV002173597 | uncertain significance | X-linked Emery-Dreifuss muscular dystrophy | 2021-08-20 | criteria provided, single submitter | clinical testing | This sequence change replaces tyrosine with cysteine at codon 167 of the EMD protein (p.Tyr167Cys). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and cysteine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with EMD-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. |

Ambry Genetics | RCV003303357 | SCV004005723 | uncertain significance | Cardiovascular phenotype | 2023-06-15 | criteria provided, single submitter | clinical testing | The p.Y167C variant (also known as c.500A>G), located in coding exon 6 of the EMD gene, results from an A to G substitution at nucleotide position 500. The tyrosine at codon 167 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
