PTPRR and psoriasis: Of the remaining 76 SNPs within the genes coding sequences, as many as 16 were located in the FTO gene, 3 SNPs were located in the PTPRR gene, and 2 SNPs each in C1orf227 (SPATA45), C5orf64, PAG1, RP11-2O17.2, RREB1, and TFCP2. Using the FUMA GWAS method, we selected 11 loci in the coding and non-coding regions of the genome related to the body mass index in the study group (considering the division into type I and type II psoriasis) (Table 1; Figure 2).
