Hypoalgesic inflammatory bowel disease (IBD) may provide critical insights into human abdominal pain. This condition was previously associated with homozygosity for a polymorphism (rs6795970, A1073V; 1073 val/val ) related to Na v 1.8, a voltage-gated sodium channel preferentially expressed on nociceptors. It was unclear whether this relationship existed for both Crohn’s disease (CD) and ulcerative colitis (UC). This study evaluated a larger, carefully phenotyped IBD cohort to investigate this question.
