Abstract

The K121Q polymorphism of the human plasma cell membrane glycoprotein 1 (PC-1) gene is known to be associated with diabetes mellitus type 2 in some populations studied, with contradictory results. The purpose of the present study was to examine a possible association between the presence of diabetes and the PC-1 K121Q polymorphism in a German Caucasian population. Associations between the polymorphism and various metabolic and anthropometric parameters were also examined. The presence of the K121Q variant was investigated using polymerase chain reaction restriction fragment-length polymorphism in 402 subjects with diabetes (231 men, 171 women, age 63±11 yrs, body mass index 28.7±5.1 kg/m2) and in 432 age- and sex-matched controls (247 men, 185 women, age 64±7 yrs, BMI 26.5±3.7 kg/m2). Ninety-seven subjects were carriers of the K121Q polymorphism in the control and 110 in the diabetic group (allelic frequency 11.9% and 14.7%, respectively, P=0.25). The polymorphism had no significant influence on the presence of atherosclerotic disease, body mass index, and blood pressure, both, in diabetics and in non-diabetic controls. Our data suggest that the K121Q polymorphism of the PC-1 gene is not associated with diabetes, obesity, hypertension or atherosclerosis in a German Caucasian population.
