GcT (Toulouse): A Fast Variant of the Group-Specific System in an Pyrenean Family

Abstract

In the course of a genetic investigation carried out in a Pyrenean population, a family with a new allele of the Gc system was found. Electrophoretic analysis revealed a faster migrating variant with a double band pattern. Presumably, this variant represents a mutant of the Gc^1 allele. The variant is transmitted as an autosomal codominant trait. This additional allele at the Gc locus is named Gc^T (Gc^Toulouse ).
