Mild alpha thalassaemia diseases

Description

A disease caused by genetically inherited factors affecting the alpha chain of the haemoglobin molecule. This disease is characterised by structural abnormalities of the haemoglobin molecule. This disease may present with mild anaemia: pallor, fatigue, shortness of breath. Confirmation is by identification of changes to the alpha chain by genetic testing.
