The GluAsp or AspAsp genotype of the Glu298Asp polymorphism was significantly associated with IHD, but not albuminuria in these Japanese diabetic subjects.
Using robust family-based association tests specifically designed for the study of complex diseases, we found no evidence that the G894T polymorphism of the eNOS gene has a significant role in the development of IHD in our population.
In this context, a genetic association study was carried out between two eNOS polymorphisms (the ecNOS4a/b VNTR and the G894T substitution) in a sample of 101 nuclear families having one affected offspring of ischemic heart disease (IHD).
