Pure red-cell aplasia. Occurrence in three generations
This paper describes a case of pure red-cell aplasia in a child whose mother and grandfather also had the disorder. A raised haemoglobin F level was documented in the child and his mother in remission, and in a sibling who was not anaemic. Further support is provided for the theory that this disorder is inherited as a autosomal dominant with variable expressivity, and that a raised haemoglobin F level in a family member who is not anaemic is a genetic marker for pure red-cell aplasia.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
