Furthermore, corroborating our results is a study using Mendelian randomisation, which showed that serum testosterone predicted by nine genetic variants from the JMJD1C gene region in men from the UK Biobank was not associated with myocardial infarction (odds ratio: 1.17, 0.78–1.75) in men, nor women 0.91 (0.43–1.91) [19]. Here, JMJD1C is linked to myocardial infarction.
