Another study on the same problem identified a direct significant correlation between the G1P3 plasmatic expression levels and body mass index (p = 0.009) and an inverse significant correlation with age (p = 0.034) in 120 patients with psoriasis compared to 120 healthy volunteers using quantitative real-time PCR, suggesting the potential application of targeted therapy in a personalized medicine approach based on this specific axis [16]. This evidence concerns the gene IFI6 and psoriasis.
