Single Nucleotide Polymorphisms in Selected Genes in Inflammatory Bowel Disease.

ABSTRACT: Introduction:Inflammatory bowel disease (IBD) is a complicated, multifunctional disorder characterized by chronic, recurring inflammation of the digestive tract. The two main types of IBD are ulcerative colitis (UC) and Crohn's disease (CD). The aim of the study was to determine single nucleotide polymorphism in fragments of the genes CARD15/NOD2 and DLG5 in patients from the Lublin Voivodeship. Patients and Methods:The study was carried out in Lublin (Poland) in 2016. 27 individuals participated in the research. The research group comprised 9 patients with a diagnosis of Crohn's disease and 9 with ulcerative colitis, aged 20 to 48, and 9 healthy volunteers. Results:No SNPs were confirmed for the CARD15/NOD2 gene fragment, but a substitution (T>C) was found in the DLG5 gene in a Crohn's disease patient. Conclusion:Absence of extraintestinal symptoms in patients with Crohn's disease may be associated with the absence of CARD15/NOD2 SNPs. The study suggests that SNPs (T>C substitution) affect the function of the DLG5 protein and thus play a role in the development of IBD, in particular Crohn's disease. The analysis presented is a pilot study due to the small number of samples.
