首先是最好玩的祖源分析,这个是目前解读的最完善的一个。自从1987年美国遗传学家Rebecca Cann等于在《Nature》上发表了文章《Mitocondrial DNA and Human Evolution》,奠定了“非洲夏娃学说”,开启了分子人类学时代,从此,人类迁徙研究进入了快车道。而相应的,祖源分析也成为大热。
The ALDH2 gene has a common polymorphism, rs671 G→A, in East Asians, resulting in a Gly-to-Lys amino acid substitution in exon 12 of the ALDH2 that decreases the activity of alcohol-metabolizing enzymes. People who possess the AG or AA genotype tend to drink less due to alcohol flush responses
rs5848(T;T) found a 3.2-fold increased risk vs C-allele carriers (95% CI: 1.50-6.73,
p=0.003) for ubiquitin- and TAR DNA-binding protein 43 -positive frontotemporal
dementia (ref 3)
