Genes affected

EMD (HGNC:3331): (emerin) Emerin is a serine-rich nuclear membrane protein and a member of the nuclear lamina-associated protein family. It mediates membrane anchorage to the cytoskeleton. Dreifuss-Emery muscular dystrophy is an X-linked inherited degenerative myopathy resulting from mutation in the emerin gene. [provided by RefSeq, Jul 2008]

The c.495G>T variant (also known as p.T165T), located in coding exon 6 of the EMD gene, results from a G to T substitution at nucleotide position 495. This nucleotide substitution does not change the threonine at codon 165. Based on data from gnomAD, the T allele has an overall frequency of 0.0005% (1/182896) total alleles studied, with no hemizygotes observed. The highest observed frequency was 0.001% (1/81705) of non-Finnish European alleles. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
