JMJD1C and myocardial infarction: Table 1 shows that serum testosterone predicted by nine genetic variants from the JMJD1C gene region in men from the UK Biobank was positively associated with thromboembolism (odds ratio 2.09, 95% confidence interval 1.27 to 3.46) and heart failure (7.81, 2.56 to 23.81), but not with myocardial infarction (1.17, 0.78 to 1.75).
