Folic acid dependent hypersarcosinaemia

W Blom, J Fernandes

    Clinica Chimica Acta; International Journal of Clinical Chemistry
    |January 15, 1979
    PubMed
    Summary

    This study identifies a rare metabolic disorder, hypersarcosinaemia, linked to sarcosine dehydrogenase deficiency. Folic acid therapy effectively reduced sarcosine excretion, indicating a folic acid-dependent form of the condition.

    Area of Science:

    • Biochemistry
    • Metabolic Disorders
    • Genetics

    Background:

    • Hypersarcosinaemia is a rare inborn error of metabolism.
    • It stems from a deficiency in the sarcosine dehydrogenase complex.
    • This complex is crucial for converting sarcosine to glycine, utilizing tetrahydrofolate as a formaldehyde acceptor.

    Observation:

    • A patient diagnosed with hypersarcosinaemia underwent prolonged therapy.
    • The therapy involved the administration of folic acid.
    • Urinary sarcosine excretion levels were monitored throughout the treatment period.

    Findings:

    • Prolonged folic acid therapy demonstrated a significant impact on urinary sarcosine excretion.
    • The observed reduction in sarcosine levels suggests a direct link between folic acid and the metabolic pathway.
    • This leads to the conclusion that the patient exhibits a folic acid-dependent form of hypersarcosinaemia.

    Implications:

    • This finding highlights a potential therapeutic strategy for specific cases of hypersarcosinaemia.
    • It underscores the critical role of folic acid metabolism in managing certain inborn errors of metabolism.
    • Further research into folate-dependent metabolic pathways could reveal new diagnostic and therapeutic targets.
