BACKGROUND: Acne vulgaris is a multifactorial disease of the skin. Several studies have shown that sebocyte proliferation and/or lipogenesis, as well as inflammatory reactions, may be regulated by peroxisome proliferator-activated receptor (PPAR)γ-mediated pathways.
AIM: To investigate whether the Pro12Ala polymorphism of the PPARγ gene might be associated with the risk of acne, and to assess the effect of this polymorphism on acne severity.
METHODS: This case-control study enrolled 100 patients with acne and 100 apparently healthy subjects. The clinical grade of acne was assessed using the Global Acne Grading System. We used PCR to identify the presence of the Pro12Ala polymorphism in exon 2 of PPARγ.
RESULTS: Our results revealed a statistically significant difference (P = 0.001) in the genotype distribution between patients and controls, with higher incidence of the Pro/Ala genotype in controls (51%) than in patients (28%). A statistically significant association (P < 0.001) between disease severity and genotype distribution was found, indicating that the Pro/Ala genotype is less prevalent in patients with severe acne.
CONCLUSIONS: Our results suggest that that the Ala allele might be a protective factor against acne development or may attenuate acne severity.
