Background: Psoriasis known as a chronic inflammatory skin disease is accompanied by metabolic disorders such as obesity, diabetes, and dyslipidemia. Vaspin (a serine protease inhibitor derived from visceral adipose tissue) is a newly identified adipokine and a link between inflammation and obesity has been reported. We aimed to determine whether vaspin gene polymorphism is associated with the development and/or clinical features of psoriasis vulgaris. Methods: Our study group consisted of 96 psoriasis vulgaris patients and 100 matched controls. Vaspin rs2236242 gene was genotyped using PCR. Results: The vaspin genotypes showed a meaningful difference between psoriasis and control groups (p = 0.02). The frequency of the vaspin rs2236242 TT genotype was lower in psoriasis patients than in control participants (p < 0.05). The TA genotype was associated with a 2.38-fold increased risk of psoriasis compared to the TT genotype (p = 0.007, odds ratio: 2.38; 95% confidence interval: 1.25-4.55), but not the AA genotype. All subjects were the Turkish population, the study in other populations is needed and the sample size was small in number. Conclusion: Our study demonstrated that vaspin rs2236242 polymorphism is related to psoriasis in the Turkish population. Polymorphisms of the vaspin gene might serve as diagnostic biomarkers of psoriasis.
