Genetic showdown: can full genome sequencing outsmart rare gut disease?

This study tests whether whole genome sequencing (looking at all DNA) finds more answers than whole exome sequencing (looking at just the protein-making parts) for children with long-lasting diarrhea and gut problems. About 180 children will be randomly assigned to one test or the other. The goal is to see which test leads to more accurate diagnoses and helps doctors choose better treatments.
