Sentences with phrase «near a gene called»

The variant lies near a gene called telomerase RNA component, or TERC, and earlier studies in animals have shown that low TERC expression is associated with shorter telomeres, and faster biological aging.

For example, domestication had seemingly altered 13 places near a gene called SOX2, which helps maintain cells destined to become part of the nervous system.

The other big hit, the team reports in the journal PLoS Genetics, was a variant near a gene called AHR, which regulates how CYP1A2 is expressed.
