Haemoglobin Disorders

Haemoglobin disorders or haemoglobinopathies are a group of conditions affecting the human blood – more specifically an important substance or protein called haemoglobin contained in the red blood cells, hence the name haemoglobin disorders or haemoglobinopathies.

Haemoglobin is a protein that consists of the alpha (α) and beta (β) parts or chains and which are in turn produced by the α-globin genes and β-globin genes respectively. Hence the diseases caused by haemoglobin abnormality either with regards to its production or its structure are divided into α-chain diseases (or α-globin gene) diseases, such as α-thalassaemia, and β-chain (β-globin gene) diseases, such as β-thalassaemia major and sickle cell disease.

These genes are found on chromosomes 16 and 11 respectively, producing equal amounts of α and β chains respectively which match together to α2β2 to produce the normal adult haemoglobin (HbA, α2β2).

Many diseases in humans are caused by abnormalities in the blood and these are categorized according to the component of the blood which is affected: white cell diseases, platelet diseases and red cell diseases.
