Abstract

We describe a cohort of 25 Iranian patients with infantile inflammatory bowel disease (IBD), 14 (56%) of whom had monogenic defects. After proper screening, patients were referred for whole exome sequencing (WES). Four patients had missense mutations in theIL10 RA, and one had a large deletion in theIL10 RB. Four patients had mutations in genes implicated in host:microbiome homeostasis, includingTTC7Adeficiency, and two patients with novel mutations in theTTC37andNOX1. We found a novel homozygous mutation in theSRP54in a deceased patient and the heterozygous variant in his sibling with a milder phenotype. Three patients had combined immunodeficiency: one with ZAP-70 deficiency (T+B+NK-), and two with atypical SCID due to mutations inRAG1andLIG4. One patient had aG6PC3mutation without neutropenia. Eleven of the 14 patients with monogenic defects were results of consanguinity and only 4 of them were alive to this date.
