Using gene-mapping techniques, the researchers identified a small stretch of DNA on chromosome 2, where the disease-causing gene was thought to reside.

研究人员运用基因制图技术鉴定了2号染色体上的一小段DNA，而通常认为致病基因就存在于该染色体。

Reporting in Nature Genetics, researchers said genetic variants on chromosome 2 and on chromosome 16 May increase the risk of estrogen-receptor-positive breast cancer.

据《自然遗传学》报道，研究人员宣称2号染色体和16号染色体发生基因变异会增加雌激素受体阳性的乳腺癌发病率。

So far, the large-grain dominant gene has not reported. Thus this research is the first to map a large-grain dominant gene on the chromosome 2 in rice, which was temporarily designated as gl-2.

目前对于长粒主效显性基因定位尚未见报道，因此本研究为首次将一长粒主效显性基因定位于第二染色体上，暂命名为GL - 2。
