TY - JOUR ID - 845547 AU - Bienertová Vašků, Julie - Vašků, Vladimír - Vašků, Anna - Bienert, Petr PY - 2009 TI - Genetic variants of the proopiomelanocortin (POMC) gene: association with psoriasis susceptibility PB - Nature Publishing Group, Macmillan Publishers Ltd CY - USA KW - proopiomelanocortin KW - gene KW - psoriasis KW - association study KW - polymorphism N2 - Psychological distress has been for long known to substantially aggravate inflammatory skin diseases such as psoriasis. Alterations in functioning of the Hypothalamic-Pituitary-Adrenal (HPA) axis, where POMC plays the crucial role, have been previously suggested to be involved in development of psoriasis. However, there is little evidence of impaired response of the HPA axis on environmental stimuli due different individual genetic background. Therefore, the aim of the study was to investigate possible effects of RsaI (rs3754860) and C1032G (rs1009388) polymorphisms in the non-coding regions of POMC gene on psoriasis and its related factors. We examined the total of 433 patients with psoriasis vulgaris and 403 healthy controls of similar age and gender distribution. No statistically significant differences were observed when genotype frequencies or allele distributions of the psoriatic group were compared to those of healthy controls. In the multivariate modeling, the RsaI polymorphism was significantly associated with the early onset of the disease (beta = -0.10, P = 0.04) and with the staging of the disease (beta = -0.25, P = 0.00003); whereas the lowest staging was associated to the "--" genotype. Moreover, RsaI was also associated with the personal history of allergy (beta= 0.15, P = 0.02), whereas the ++ genotype represented the risk variant for personal allergy history. Furthermore, common haplotypes in POMC gene were identified, with no case-control differences observed. The "-G" haplotype was significantly associated with the highest rate of recurrent tonsillitis in psoriasis patients (beta= 0.13, P = 0.005). To conclude, our results indicate that the investigated POMC gene variants could act as specific risk factors for psoriasis-related anamnestic factors, relevant for susceptibility to psoriasis in general.
