Abstract

Ultrafiltrates of human myoglobin from 200 individuals were examined by starch-gel electrophoresis. Only two variants, MbAberdeen and MbAnnapolis, of the commonly occurring myoglobin Mb+ were encountered. Each variant is apparently inherited as an autosomal codominant. Heterozygotes for either mutation lack apparent muscular disease. Combined electrophoresis and chromatography of MbAnnapolis indicate a loss of arginine at a position near the C-terminal portion of the molecule.
