Write answer in between .Q:A 6-month-old boy presents with decreased growth, pigmented retinopathy, hemolytic anemia, and peripheral neuropathy. You suspect that these signs are the result of a vitamin deficiency leading to increased fatty acid oxidation. Which of the following is most likely responsible for this patients symptoms?? A: Pernicious anemia, B: Abetalipoproteinemia, C: Goat milk ingestion, D: Hartnup disease, E: Excessive boiling of formula,  <response>: Based on the clinical findings of decreased growth, pigmented retinopathy, hemolytic anemia and peripheral neuropathy in a 6-month-old infant, this appears to be a case of vitamin E deficiency. The decreased growth and neurological findings are consistent with developmental delay and neurologic impairment seen in vitamin E deficiency. The hemolytic anemia and retinopathy point towards increased oxidative stress and red blood cell membrane instability due to lack of the antioxidant effects of vitamin E. The choices given describe various causes of malabsorption or deficiency of specific vitaminsnutrients. Pernicious anemia leads to vitamin B12 deficiency. Abetalipoproteinemia causes fat malabsorption and vitamin E deficiency. Goat milk and excessive boiling of formula can both lead to biotin deficiency. Hartnup disease leads to tryptophan malabsorption. Of these, abetalipoproteinemia is the most likely diagnosis given this clinical presentation and the suspicion that increased fatty acid oxidation from vitamin E deficiency is contributing to the symptoms.B: Abetalipoproteinemia
