Haemoglobin SH disease in a Bahraini women detected at pregnancy

A rare combination of haemoglobin-S and haemoglobin-H disease was observed in a Bahraini woman during her pregnancy. She had presented with anaemia not responding to usual haematenics. The haematological and genetic studies suggested haemoglobin-H most likely to be due to non deletional type of alpha thalassemia, which is different from deletional variants present in other parts of the world
