Comparing whole genome sequencing and whole exome sequencing for congenital diarrhea
Official title: A Randomized, Controlled Trial of the Effectiveness of Whole Genome Sequencing Versus Whole Exome Sequencing for Screening Patients With Congenital Diarrhea and Enteropathy (CODESeq)
Run by Children's Hospital of Fudan University · NCT04528303 · Data updated 2026-11-12
This study is testing if whole genome sequencing can help doctors better diagnose and treat patients with congenital diarrhea compared to whole exome sequencing.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients with chronic diarrhea lasting more than 2 months and who have consent from their parents or legal guardians.
✕Probably not a fit
Patients with chronic diarrhea caused by specific infections or those with previously confirmed monogenic diarrhea may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to determine whether whole genome sequencing (WGS) can improve diagnostic rates and outcomes for patients with congenital diarrhea and enteropathy (CODE) compared to whole exome sequencing (WES). A total of 180 patients will be enrolled in a randomized controlled trial, where they will receive either WGS or WES. The goal is to evaluate the potential benefits of WGS in guiding precision medicine for these patients.
Why it matters
Potential benefit: If successful, this study could lead to improved diagnosis and treatment options for patients suffering from congenital diarrhea and enteropathy.
How similar studies have gone: Other studies have shown promising results with whole genome sequencing in various genetic conditions, suggesting potential success for this approach in congenital diarrhea.
