美国马萨诸塞总医院神经病医师研究小组可能发现了遗传性疾病杭廷顿氏舞蹈病的原因。此病表现为体格和人格逐渐发生不可逆的退化,但症状一般到中年后才出现,此时病人可能已把性格传给了子女。从一代传给下一代的不肯定性是根除此病的障碍之一。用DNA探针检查疾病携带者可能有些帮助,但最大的问题是无法阻止患者的病变现象,也无人了解其病因,或不了解为杭廷顿氏舞蹈病编码的基因。
The Massachusetts General Hospital neuropathic team may have discovered the cause of the Huntington’s disease, a hereditary disease. The disease manifests itself in an irreversible deterioration of the physique and personality, but the symptoms generally appear after middle age, at which time the patient may have passed the character to the child. The uncertainty that is passed from one generation to the next is one of the obstacles that eradicate the disease. It may be helpful to check for disease carriers with DNA probes, but the biggest problem is the inability to stop the patient’s pathology, the etiology of the disease, or the genes that encode for Huntington’s disease.
