Hemoglobin Kenitra α₂β₂69 (E13) Gly→Arg. A new β Variant of Elevated Expression Associated with α-Thalassemia, Found in a Moroccan Woman

Abstract

Hemoglobin Kenitra is a new variant of the β chain α₂β₂ 69 (E13) Gly→Arg which does not produce any clinical symptoms. It is a slow-moving hemoglobin with a distinctive pattern of electrophoretic mobilities. The stability test was negative. Oxygen affinity studies were not performed. It was found in association with α-thalassemia and microcytosis, but paradoxically a high expression of the variant (55%) was observed.
