Ankyrin repeat and zinc-finger domain-containing 1 mutations are associated with infantile-onset inflammatory bowel disease.

ABSTRACT: Infantile-onset inflammatory bowel disease (IO IBD) is an invalidating illness with an onset before 2 years of age and has a complex pathophysiology in which genetic factors are important. Homozygosity mapping and whole-exome sequencing in an IO IBD patient and subsequent sequencing of the candidate gene in 12 additional IO IBD patients revealed two patients with two mutated ankyrin repeat and zinc-finger domain-containing 1 (ANKZF1) alleles (homozygous ANKZF1 R585Q mutation and compound heterozygous ANKZF1 E152K and V32_Q87del mutations, respectively) and two patients with one mutated ANKZF1 allele. Although the function of ANKZF1 in mammals had not been previously evaluated, we show that ANKZF1 has an indispensable role in the mitochondrial response to cellula
