A polymorphism of α-L-fucosidase has been found in human urine by isoelectric focusing technique. Three phenotypes αFUC 1, αFUC 2-1, and αFUC 2 were determined by two common alleles, αFUC1 and FUC2. Paired leucocyte and urine samples from the same individuals were analyzed, and it was found that the phenotypes of the pairs were identical. Estimated frequencies of αFUC1 and αFUC2 among Japanese were 0.766 and 0.234, respectively.
