What the study found

Who was studied 397,338 European ancestry individuals.

The effect Each copy of the T allele shifted the measure 0.0219 lower (95% confidence interval 0.017-0.027); p = 1 × 10−15.

How common The T allele had a frequency of about 83% in the people studied.

Where it sits Chromosome 5, band 5p12 — between genes, 135.4 kb from HCN1.
