摘要：The present world-wide interest in haemoglobinopathies and allied disorders has given rise to a very considerable literature over the past two decades. This communication reviews this literature in so far as it refers to the Indian subcontinent. The most common abnormality is thalassaemia, which has been discovered in all regions under consideration: India, Pakistan, Nepal, Bhutan and Ceylon. Haemoglobins S, D and E are also quite common: Hb S has been found mostly in the aboriginal tribes, Hb D in Gujaratis and Punjabis and Hb E in Bengalis, Assamese and Nepalese. A few instances of haemoglobins F, H, J, K, L and M have also been reported. However, there remain many population groups to be investigated. Studies of the distribution of glucose-6-phosphate dehydrogenase deficiency are also reviewed, and the correlation between the various haemoglobin disorders and various environmental factors is discussed, but it is pointed out that the relevant data are still insufficient to allow any definite conclusions to be drawn.
