Mutation Spectrum of NOD2 Reveals Recessive Inheritance as a Main Driver of Early Onset Crohn’s Disease
- Scientists from a medical school in Southern California discovered that a mutation in the PTPN2 gene contributes to worsening iron deficiency and anemia in individuals with Crohn’s disease.
- They found that this mutation disrupts blood proteins regulating iron levels, explaining why some inflammatory bowel disease patients remain iron-deficient despite treatment.
- The study included deleting PTPN2 in mice, which caused anemia and poor iron absorption due to reduced intestinal iron-absorbing protein levels.
- Declan McCole explained that the findings reveal an important biological process through which a person’s genetic makeup influences how effectively they absorb and manage iron, a key factor for maintaining good health.
- The findings suggest prioritizing patients with PTPN2 mutations for intravenous iron therapy to address anemia since oral iron may be poorly absorbed in these cases.

Mutation spectrum of NOD2 reveals recessive inheritance as a main driver of Early Onset Crohn’s Disease
Inflammatory bowel disease (IBD), clinically defined as Crohn’s disease (CD), ulcerative colitis (UC), or IBD-unclassified, results in chronic inflammation of the gastrointestinal tract in genetically susceptible hosts. Pediatric onset IBD represents ≥ 25% of all IBD diagnoses and often presents with intestinal stricturing, perianal disease, and failed response to conventional treatments. NOD2 was the first and is the most replicated locus assoc…
Genetic Mutation Linking Crohn’s Disease to Iron Deficiency Identified
A team of researchers at the University of California, Riverside (UCR) School of Medicine has identified a genetic mutation that disrupts iron absorption in patients with Crohn’s disease, providing new insight into the persistent anemia that affects a high percentage of people with inflammatory bowel disease (IBD). The findings, published in the International Journal of Molecular Sciences, detailed how patients carrying a loss-of-function mutati…
Genetic link found between iron deficiency and Crohn’s disease
A study led by biomedical scientists at the University of California, Riverside School of Medicine shows how a genetic mutation associated with Crohn’s disease can worsen iron deficiency and anemia — one of the most common complications experienced by patients with inflammatory bowel disease.
