Web9 mei 2024 · Homocystinuria. Homocystinuria (HCU) is a rare but potentially serious inherited condition. It means the body can't process the amino acid methionine. This causes a harmful build-up of substances in the blood and urine. Normally, our bodies break down protein foods like meat and fish into amino acids, which are the "building blocks" of protein. WebHomocysteine is an intermediary in the sulfur-amino acid metabolism pathways, linking the methionine cycle to the folate cycle. Inborn errors of metabolism that lead to homocysteinemia or homocystinuria include cystathionine beta-synthase deficiency (homocystinuria) and various defects of methionine remethylation.

Deficiencies of vitamins B6, B9 and B12 can lead to high homocysteine levels. Vitamin B12 acts as a cofactor for the enzyme methionine synthase (which forms part of the S-adenosylmethionine (SAM) biosynthesis and regeneration cycle). Vitamin B12 deficiency prevents the 5-methyltetrahydrofolate (5-MTHF) form of folate from being converted into THF due to the "methyl trap".
