The human leukocyte antigen (HLA)-Cw*07 allele is linked to ulcerative colitis susceptibility, while HLA-Cw*12 is associated with Crohn's disease risk. These findings identify potential genetic markers for inflammatory bowel diseases.
Area of Science:
- Immunogenetics
- Gastroenterology
Context:
- Inflammatory bowel disease (IBD) encompasses ulcerative colitis (UC) and Crohn's disease (CD).
- The genetic basis of IBD susceptibility is complex and involves human leukocyte antigen (HLA) genes.
Purpose:
- To investigate the association between specific HLA-Cw alleles and the risk of developing IBD.
- To identify potential IBD susceptibility genes within the HLA-Cw locus.
Summary:
- This study analyzed HLA-Cw genotypes in 100 UC patients, 73 CD patients, and 106 healthy controls using PCR-SSP.
- Results showed a significantly higher frequency of HLA-Cw*07 in UC patients (0.430 vs. 0.226) and HLA-Cw*12 in CD patients (0.356 vs. 0.123) compared to controls.
Impact:
- The findings suggest that HLA-Cw*07 may be a susceptibility allele for UC.
- HLA-Cw*12 may be a susceptibility allele for CD.
- These associations contribute to understanding the genetic underpinnings of IBD.

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.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. 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...
