Mutant Gene Discovery突变基因新发现

Chinese doctors have discovered and registered a new mutant gene for alpha-thalassemia, first of its kind worldwide, an advance that enriches the gene database to assist researches into cures for genetic disease.

中国医生已经发现并注册了一种新的α-地中海贫血突变基因，这是全球第一次发现该类型的基因，这种进步丰富了基因数据库，有助于关于遗传性疾病治疗方法的研究。

Li Youqiong and colleagues from the People's Hospital of Guangxi Zhuang Autonomous Region, discovered this gene, a 21.9, after a series of experiments on a carrier of the hereditary disease in 2011.

广西壮族自治区人民医院的李友琼医生和他的同事们在2011年对遗传性疾病载体进行了一系列的实验之后发现了这种基因，α21.9。

Thalassemia is a disease where the carrier is missing or has malfunctioning genes responsible for making hemoglobin, the blood protein that helps to carry oxygen around the body.

地中海贫血这种疾病存在以下两种问题——载体丢失或者存在有故障的负责制造血红蛋白的基因（血红蛋白有助于把氧气运输到全身）。

The hemoglobin molecule has subunits commonly referred to as alpha and beta.

血红蛋白分子一般由α亚基和β亚基组成。
