Background:
We analyzed the relationship of -794 CATT5-8 MIF polymorphisms with soluble MIF in Coronary Atherosclerotic Disease (CAD) patients.
Methods:
A total of 256 patients selected, on which 186 normal-coronary and 70 Coronary artery disease subjects, were recruited in the study (Retrospectively registered). Genotyping of -794 CATT5-8 polymorphisms were performed by PCR and DNA sequencing. Serum MIF levels were measured using an ELISA kit. Patients were classified by coronary angiogram, and CAD based on Gensini's integral degree (angiographic scoring system).
Results:
The allele frequency and genotype frequency of -794 CATT5-8 did not show any differences in normal-coronary subjects and CAD subjects. In CAD patients, serum MIF levels was lower in CATT (5) subjects than in CATT (7) subjects, while the genotype of -794 CATT5-8 did not show differences in serum MIF levels. In addition, we found a decrease in serum MIF levels in carriers of the (5/5) genotypes the -794 CATT5-8 MIF polymorphisms, although it was not significant. There was no relationship of CAD class and the allele frequency of -794 CATT5-8.
Conclusions:
This study found no association between CAD class and -794 CATT5-8 MIF polymorphisms with soluble MIF levels in CAD Subjects.
Trial Registration:
NCT01750502 (November 2012, Retrospectively registered).
