Polymorphism of fucosyltransferase 3 gene is associated with inflammatory bowel disease: a systematic review
1Department of Public Health, School of Basic Medical Science, Putian University, Putian, Fujian 351100, China.
Background:
Inflammatory bowel disease (IBD) is a condition with an unclear genetic basis. Fucosyltransferase 3 (FUT3) could potentially be linked to IBD susceptibility.
Objective:
To investigate the association between FUT3 gene polymorphisms and IBD.
Methods:
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist and Population, Intervention, Comparison, Outcomes, and Study (PICOS) guidelines, case-control studies published until April 30, 2020 was searched. Two independent reviewers conducted screening, data extraction, and quality assessment using the Newcastle-Ottawa Scale. Meta-analysis, sensitivity analysis, and Egger tests were performed using RevMan and Stata12.0.
Results:
The review included 5 articles and 12 case-control studies involving 1712 IBD patients and 1903 controls. The meta-analysis revealed the following combined odds ratios [95% confidence intervals]: rs3745635 genotype (GA+AA vs GG) 0.84 (0.72-0.97), (GG+GA vs AA) 1.93 (1.23-3.05), (GG vs AA) 2.38 (1.52-3.74), (A vs G) 0.84 (0.73-0.96); rs3894326 genotype (TA+AA vs TT) 1.03 (0.87-1.23), (TT+TA vs AA) 1.19 (0.56-2.51), (TT vs AA) 1.19 (0.56-2.51), (A vs T) 1.02 (0.86-1.20); rs28362459 genotype (TG+GG vs TT) 0.98 (0.85-1.12), (TT+TG vs GG) 1.20 (0.90-1.61), (TT vs GG) 1.21 (0.90-1.62), (G vs T) 0.96 (0.86-1.07). Sensitivity analysis indicated the stability of the results, and Egger analysis showed no significant publication bias.
Conclusions:
The rs3745635 gene polymorphism may be associated with IBD susceptibility, whereas the rs3894326 and rs28362459 gene polymorphisms may not be associated with IBD.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
