Table 3.
The variation in genotype frequency of COMT Val158Met with disease status.
| Genotype | Disease status | |||
|---|---|---|---|---|
| FM (N = 20) | RH (N = 10) | Healthy (N = 10) | Fisher exact test | |
| HH (Val/Val) | 0% (N = 0) | 50% (N = 5) | 0% (N = 0) | pvalue = 0.033 |
| HL (Val/Met) | 65% (N = 13) | 50% (N = 5) | 100% (N = 10) | |
| LL (Meth/Met) | 35% (N = 7) | 0% (N = 0) | 0% (N = 0) | |
HH represents the genotype of normal homozygous (Val/Val); HL represents the heterozygous (Val/Met); LL represents the mutant homozygous (Meth/Met); FM: fibromyalgia patients; RH: rheumatoid patients.
