However, the frequency of PPARD +294C allele was higher in our study population than in 543 healthy 50-year-old-men (15.6%) from the northern part of the greater Stockholm area [24], in normal controls (19.5%) from Chinese Anhui Province [33], in healthy Tunisian population (18.9%) [32], and in non-diabetic Germany controls (19.2%) [35]; but it was lower than in Tunisian CAD patients (32.0%) [32] and Chinese CAD patients (30.8%) [33]. Here, PPARD is linked to coronary artery disorder.
