The present study aimed to determine the association between cytokine gene polymorphisms (TGF-β1-509 C/T, TNF-α -308 G/A, IFN-γ +874 A/T) and susceptibility to AA in Egyptian patients.
To investigate the role of cytokine gene polymorphisms (IL-6/-174, TNF-α/-308, IFN-γ/+874, and TGFβ1/-509) in patients with acquired AA to assess if genotypes associated with higher or lower production were more prevalent than in established control population and to study the possible association of these genotypes with the disease severity.
Concerning TGFB1, although its polymorphisms are not related to AA susceptibility, P10L T allele (recessive model, OR = 0.18, p = .038) and CT haplotype (dominant model, OR = 5.68, p = .038) were associated with response to IST.
