定义
一种由出生后、产前的影响因素或遗传因素引起的导致血红蛋白氧亲和力低下的疾病。疾病特点是球蛋白链异常，改变了血红蛋白分子对氧的亲和力，影响肺部正常氧负荷和向组织输送氧。这种疾病可能表现为疲劳、肌肉无力、食欲不振、体重减轻、腹泻、恶心、心跳加快或四肢麻木。
A disease caused by determinants arising after birth, in the antenatal period or by genetically inherited factors leading to low oxygen affinity haemoglobin. This disease is characterised by abnormalities in the globin chains that alter the affinity of the haemoglobin molecule for oxygen, affecting the normal loading of oxygen in the lungs and delivery of oxygen to the tissues. This disease may present with fatigue, muscle weakness, loss of appetite, weight loss, diarrhoea, nausea, fast heartbeat or numbness in extremities.
