Hemoglobin G _coushatta : A New Variant in an American Indian Family

Abstract

A new hemoglobin variant, G(couhatta) (alpha2(A) beta2(iiiglu-->ala)), has been found in three generations of a family from the Alabama Coushatta Indian tribe in east Texas. The propositus suffers from an apparently unrelated, possibly genetic, agranulocytosis. According to the history and the blood grouping data there is considerable in breeding in the tribe and remarkably little admixture with other ethnic groups.
