Two types of variant albumins were detected during routine electrophoresis on cellulose acetate on 34,000 sera from patients in a relatively stable Irish population. The fast type (IRE1) (relative mobility 1.05) had a heterozygote frequency of 1/3,780, and the slow type (IRE2) (relative mobility of 0.94) had a heterozygote frequency of 1/8,500. A method for purification of the two types of variants is described. Structural study of the fast variant established a single amino acid substitution 313 lysine----asparagine (313 Lys----Asn); this variant has been reported in several European populations and also in New Guinea indigenes. However, the slow variant has a new substitution, 479 glutamic acid----lysine (479 Glu----Lys). Because it appears to be uniquely Irish, the slow variant (formerly called IRE2) has been renamed albumin Dublin. Three other albumin variants most often reported in European populations (cumulative frequency only about 1/3,500) were not detected in this study. Because of the significance of albumin genetic variants for the study of protein evolution and as an aid in identification of drug-binding sites, clinical chemists are asked to be on the alert for cases of bisalbuminemia.
