Homozygosity for the mutation Cys282Tyr in the HFE gene has recently been identified as a cause of hereditary hemochromatosis, a disorder resulting in the inappropriate absorption of iron. Approximately 10% of Caucasians are heterozygous for this mutation; however, the gene frequency in African Amer

We identified a novel missense mutation in the myophosphorylase gene (PYGM) in a Spanish patient with McArdle's disease. This homozygous T-to-C transition results in the replacement of a highly conserved tryptophan at amino acid position (aa) 797 with an arginine in the C-terminal domain of the PYGM
