Two new slow-moving variants of human serum albumin

Two new slow-moving variants of human serum albumin were found in members of two unrelated Japanese families. These variants, different from each other and from the slow-moving variants described previously, were designated albumin "Okinoerabu' and albumin "Akasaka'. The mode of inheritance of each variant was consistent with an autosomal codominant trait. A very rare type, homozygote for a variant, albumin "Okinoerabu', was also detected. The segregation data of albumin and Gc showed no discrepancy from the postulation of a linkage between these two loci.
