Homocystinuria

Homocystinuria is a rare inherited metabolic disease that affects the metabolism of the amino acid methionine. Homocystinuria is incurable and if not managed, it can result in medical complications in the eye, skeletal system, vascular system, the brain and spinal cord. Treatment includes the need to take vitamin B6, B9 (folate), B12 supplements, for the rest of their lives. A diet of low-methionine - low protein diet, with betaine is needed for those who do not respond to the supplements. People diagnosed with homocystinuria therefore must carry on board and/or checked luggage:

• Special protein substitute formulas and/or vitamins (liquid, powder or pills)
• Low protein foods
• Pharmaceutical products dedicated to Homocystinuria treatment
