The analysis revealed three candidate genes GSK3B, PTPN1, STX4 that are differentially expressed in study subjects. GSK3B was highly significant in Ps-T2D (P=0.00018, FR=-26.6), followed by Ps (P=0.0028, FR=-14.5) and T2D groups (P=0.032, FR=-5.9). PTPN1 showed significant association only with PS-T2D (P=0.00027, FR=-8.5). STX4 showed significant association with both Ps (P=0.0002, FR=-20) and Ps-T2D (P=0.0016, FR=-11.2). | De-regulation of diabetic regulatory genes in psoriasis: Deciphering the unsolved riddle.
