S ummary . Five families with δ‐thalassaemia discovered in Ehime, Japan, are presented. The δ‐thalassaemia was associated with a slight elevation of the level of Hb F in two families and with normal Hb F levels in three. Complete absence of HbA 2 was found in the homozygous probands. No abnormal clinical or haematological findings were noted in the individuals with δ‐thalassaemia.
