Core Tip
Core tip: The present review focused on the phenomenon of ethnic discrepancies in irritable bowel syndrome-related genetic studies by gathering up-to-date original research and meta-analyses. We discuss the ethnic background and its potential impacts on the inconsistent results of studies, emphasizing the consideration of ethnicity in designing and analyzing irritable bowel syndrome-related genetic investigations, especially for multi-ethnic, transnational, and cross-cultural studies.
