Haplotype frequencies of codons 62 and 158 of COMT between healthy controls and patients with RCC
| Haplotype | Control (n = 314) | RCC (n = 246) |
|---|---|---|
| 62C-158G | 224 (71.2%) | 139 (56.6%) |
| 62T-158A | 72 (22.8%) | 54 (22.0%) |
| 62T-158G | 7 (2.3%) | 33 (13.4%) |
| 62C-158A | 11 (3.6%) | 20 (8.1%) |
| P < 0.001 |
NOTE: P value is based on 62C-158G compared with other haplotypes combined.
