Human red cell galactose-1-phosphate uridylyltransferase (EC 2.7.7.12). Electrophoretically determined polymorphism in Denmark and its use in paternity cases.

Abstract

The electrophoretically detectable phenotypes of human red cell galactose-1-phosphate uridylyltransferase (GALT) were determined in 2,074 unrelated Danes. The gene frequencies were: GALT1 = 0.9233 and GALT2 = 0.0767. The segregation of phenotypes in 765 mother-child pairs was consistent with autosomal codominant inheritance. One apparent mother-child incompatibility with respect to phenotypes was observed which, however, appeared to be due to the segregation of a silent gene. The results of an investigation of 248 paternity cases are reported, and the application of the GALT polymorphism to paternity cases is discussed.
