Table 3.
Measures of linkage disequilibrium observed in a pairwise comparison of the two polymorphisms of the endothelial nitric oxide synthase (eNOS) gene among the study population.
| Variant 1 | Variant 2 | D′ | r 2 | χ 2 | Linkage disequilibrium |
|---|---|---|---|---|---|
| eNOS 4 | eNOS 7 | −0.144 | 0.0172 | 12.04 | In linkage disequilibrium |
| eNOS 4 | eNOS T786C | 0.125 | 0.0043 | 3.01 | Not in linkage disequilibrium |
| eNOS 7 | eNOS T786C | −0.309 | 0.0054 | 3.78 | Not in linkage disequilibrium |
D′: Lewontin's standardized disequilibrium coefficient.
r 2: squared correlation coefficient for pairwise linkage disequilibrium between two loci.
χ 2: Chi-square value.
