Haemoglobin Siriraj, β-7 (βA4) Glu Lys, in a Chinese Subject in Taiwan

. Haemoglobin Siriraj, β-7 GluLys, was reported in members of a Thai family by Tuchinda, Beale and Lehmann [Brit. med. J. 1: 1583–1585, 1965]. The same variant now is reported in a normal Chinese subject originating from the Chinese province of Honan. Relative amounts of haemoglobins Ao and Siriraj were 67 to 33. Incidence of Siriraj in Chinese subjects is low; only one subject was found among 160,000 Chinese tested.
