Brief Summary

Inflammatory bowel disease(IBD) is a chronic inflammatory condition for gastrointestinal tract. Regarding its pathogenesis, there has been numerous studies to reveal the complex association between genetic and environmental factors. In Korea, the incidence of IBD is growing rapidly but genetic studies solely including patients with Korean descent were not sufficient enough. Therefore, the investigators planned to conduct genetic and fecal microbial analysis for the 60 individuals from 30 Korean IBD families to find out the pathogenesis of IBD.

Outcome Measures

Primary Outcomes (4)

  • Rare genetic variants of inflammatory bowel disease

    Results from whole genome sequencing of blood samples of study participants. Planned to compare with the previously reported variances.

    Three months after the sample collection

  • Common genetic variants of inflammatory bowel disease

    Results from genome-wide single nucleotide polymorphism array of blood samples of study participants. Planned to compare with the previously reported variances.

    Three months after the sample collection

  • Genetic risk score of inflammatory bowel disease

    Results from genome-wide single nucleotide polymorphism array of blood samples of study participants. Planned to compare with the previously reported variances.

    Three months after the sample collection

  • Fecal microbiome composition of each study subjects

    Microbial diversity measured from 16S RNA sequencing datas of fecal microbiomes.

Sampling MethodNon-Probability Sample
Study Population

The investigators are planned to study family members with IBD(Crohn's disease or ulcerative colitis). They are all Koreal descent and study candidates are two patients from each 30 families. As a healthy internal control, another family member without IBD history will be also enrolled.

You may qualify if:

  • individuals from 30 families of Crohn's disease or ulcerative colitis.
  • Unaffected 30 individuals from each family as healthy internal control.

You may not qualify if:

  • Person with history of using antibiotics or probiotics within previous 4 weeks.
