一支国际研究小组找到了一种遗传性心脏病的基因标记。这支由哈佛大学医学院、伦敦圣乔治医院,蒙特利尔皇家维克多医院和圣路易斯华盛顿大学的科学家们组成的小组研究了家属系统心脏肥大的心肌病,这是一种心脏内壁变厚而致命的心脏病。科学家们通过一个加拿大家庭好几代人中的78名成员,跟踪研究了这种不常见病的发生率。虽然科学家们还没有可靠地找到这种病的基因,但是他们已经追捕到它的染色体14的长臂并找到了一种基因标记,这种标记跟随基因一起遗传。可以确信,有这种标记的人将会遭受心脏紊乱的痛苦。
An international team found a genetic marker of hereditary heart disease. A team of scientists from Harvard Medical School, St. George’s Hospital in London, Royal Victor Hospital in Montreal and Washington University in St. Louis studied cardiomyopathy in a family with cardiomegaly, a thickened and fatal inner wall of the heart. heart disease. Scientists tracked the incidence of this unusual disease through 78 of several generations in a Canadian family. Although scientists have not yet reliably found the gene for the disease, they have chased down the long arm of its chromosome 14 and have found a genetic marker that is inherited with the gene. It is safe to assume that people with this type of markup will suffer from heart disturbances.
