Analysis of the selenoprotein P (rs7579) gene polymorphism and expression in patients with chronic pancreatitis combined with hypothyroidism

Background. The specific role and place of genetic factors in the development of chronic pancreatitis and hypothyroidism, which determine the activity of glutathione antioxidant protection, have not been clarified. They are interconnected with changes in the fat and carbohydrate metabolism, and also affect the transport and signaling pathways of key nutrients for the work of the immune, endocrine and nervous systems. The purpose of the study is to investigate the selenoprotein P (SEPP1) (rs7579) gene polymorphism and expression in patients with chronic pancreatitis combined with hypothyroidism. Materials and methods. Forty-nine patients with chronic pancreatitis and hypothyroidism and 30 practically healthy individuals passed the screening stage. The SEPP1 (rs7579) gene polymorphism was determined by the polymerase chain reaction. Results. The study showed that out of 98 isolated alleles in patients with chronic pancreatitis and hypothyroidism and 60 alleles of the control group, the G allele of the SEPP1 gene (rs7579, 25191G/A) dominated over the A allele: in the examined patients — by 34.7 % (χ2 = 23.59; p
