Two novel mutations in the myophosphorylase gene in a patient with McArdle disease.
We identified two novel mutations in exon 2 of the myophosphorylase gene in a 33-year-old German women with McArdle disease. The patient was compound heterozygous for a novel nonsense mutation at codon 84 changing tyrosine to stop codon (Y84X) and for a novel missense mutation at codon 93 changing arginine to tryptophan (R93W). These mutations are the first to be described in exon 2 and expand the genetic heterogeneity in patients with McArdle disease.
