We report on a Japanese family affected by Emery-Dreifuss muscular dystrophy carrying a novel mutation of the emerin (STA) gene. The cardinal clinical feature of the family was cardiac conduction block and mild myopathy. A deletion of 11 bp with a frameshift was identified in exon 6, causing truncation of the predicted protein. The relationship between mutation and phenotype is discussed.
