  "id": "MLC-T-CHM-008678",
  "term": "Pernicious anemia",
  "field": "Chemistry",
  "definition": "An autoimmune condition characterized by a deficiency in vitamin B12, caused by the body's inability to absorb the vitamin from the gastrointestinal tract. This malabsorption results from the immune system attacking intrinsic factor, a protein necessary for B12 uptake, or the parietal cells that produce it. Diagnosis often involves measuring vitamin B12 levels and intrinsic factor antibodies.",
