Members of a Cambodian family with an undiagnosed hypochromic, microcytic anaemia were found by haemoglobin and DNA analysis to have five interacting globin gene abnormalities. One child has Hb E and typical Hb H disease, while his mother has the form of Hb H disease associated with Hb Constant Spring interacting with Hb E. Quantitation of Hbs E and A2 by globin chain separation and triton/urea gel electrophoresis support the concept that Hb H/Constant Spring disease is a more severe form of alpha thalassaemia than Hb H disease. This family illustrates how the remarkably high prevalence of globin gene abnormalities in Southeast Asians can give rise to a series of atypical thalassaemic phenotypes, and how they can be defined by direct globin gene analysis.
