Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]

open access: yes, 2000
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

Upper and small bowel Crohn's disease in Brazilian children: Phenotypic characteristic and surgical risk

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Upper and small bowel Crohn's disease (U‐SBCD) represents a clinically aggressive phenotype with high complication rates yet remains diagnostically challenging. In low‐ and middle‐income countries (LMICs), limited inflammatory bowel disease (IBD) awareness contributes to diagnostic delays, but their impact on U‐SBCD outcomes remains
