A gipsy patient was studied for jaundice and splenomegaly. The haematological studies disclosed a picture of chronic haemolytic disease. The haemoglobin electrophoresis on cellulose acetate at pH 8.6 presented a single haemoglobin band of slow mobility located on the HbA2 zone. The structural and immunologic studies of such haemoglobin showed a homozygous C haemoglobin. The family study allowed us to find other members with heterozygous HbC plus two identical twins carrying double HbC/.beta.+ thalasaemia heterozygosity. The analytical data and the molecular and epidemiological data of this mutation are commented.
