Vitamin D receptor affects risk of myocardial infarction and diabetes

Vitamin D related genes could increase the risk of type 2 diabetes and myocardial infarction, according to Ieva Martinaityte‘s PhD thesis.


  1. The C allele of rs7968585 increases the risk of myocardial infarction by 14 %.
  2. The same genetic variant increases the risk of type 2 diabetes with 25 %.
  3. The C allele affects risk negatively in both persons with high and low levels of vitamin D.

(1) Genetic variations in the vitamin D receptor predict type 2 diabetes and myocardial infarction. The less common C allele of rs7968585 is linked to increased risk of both diseases when compared to the common T allele.

The analysis includes almonst 8500 participants in the Tromsø 4 Study in 1994 and 1995. More than 1000 developed diabetes by the end of 2011, whereas 2287 had a myocardial infarction. The C allele increased the risk of diabetes by 25 % and the risk of myocardial infarction by 14 %. There was no significant interaction between vitamin D levels in blood and the rs7968585 genotype, and the gene seems to affect risk negatively independent of D vitamin status.

(2/3) The rest of the PhD thesis focuses on D vitamin receptor genes and bone health, and on D vitamin status one year after cessation of D vitamin supplements.
