The renal impairment that leads to renal anaemia can have various causes. Inherited genetic predispositions are seldom unequivocally involved, and even when they are, the relevant genes have not necessarily been identified.
What is important is to distinguish renal anaemia from the single-gene diseases sickle-cell anaemia and thalassaemia or Mediterranean anaemia. This means that renal anaemia is not transmitted by a mutated gene.
Anaemia is often the result of an underlying illness such as chronic renal failure or cancer. Common causes of chronic renal failure are type-2 diabetes and high blood pressure (hypertension). People who suffer from these underlying diseases carry a higher risk of developing renal anaemia. |
