| ethnic differences in polymorphisms of tumor necrosis factor-alpha, interleukin-10, and transforming growth factor-beta1 genes in patients with chronic hepatitis c virus infection. | ethnic differences in the outcome of hepatitis c have been described. our aim was to investigate ethnic differences in the distribution of genotypes associated with polymorphisms of the tumor necrosis factor-alpha promoter, interleukin-10 promoter, and transforming growth factor-beta1 leader sequence in patients with hepatitis c. genomic dna was obtained from 71 egyptians and 67 caucasians (hepatitis c and control patients). amplification of appropriate gene segments was followed by direct seque ... | 2004 | 15100460 |
