Gene Mutation Found to Worsen Iron Deficiency in Crohn's Patients
Scientists have discovered a genetic link to iron deficiency in people with Crohn's disease, an illness that affects the intestines.
They found that a specific gene, PTPN2, when mutated, disrupts the body's ability to absorb iron properly.
This can lead to anemia, making patients feel tired and weak.
The study showed that this mutation affects proteins that help manage iron levels in the blood.
This finding could explain why some patients with Crohn's disease still lack iron despite taking supplements.
The research helps understand how genes impact iron absorption and overall health.
Researchers identified a gene mutation linked to iron deficiency in Crohn's patients.
The mutation is in the PTPN2 gene, affecting blood protein regulation of iron.
The study involved serum samples from patients with inflammatory bowel disease (IBD).
Loss-of-function mutations in PTPN2 led to reduced iron absorption.
Findings explain why some IBD patients remain iron-deficient despite supplementation.
