XX. SCF LAYMAN’S SUMMARY
Homocystinuria is a rare inherited metabolic disorder in which the body cannot properly process the amino acid homocysteine. As homocysteine accumulates, it damages blood vessels, connective tissues, eyes, bones, and the nervous system. People with the condition often develop lens dislocation, skeletal abnormalities, developmental problems, and a greatly increased risk of dangerous blood clots. Early diagnosis and treatment with dietary management, vitamins, and homocysteine-lowering therapies can significantly improve outcomes. SCF interprets Homocystinuria as a sulfur-metabolism communication disorder involving biochemical congestion, endothelial injury, and loss of synchronized methylation and detoxification networks.
