Remethylation Disorder Therapeutic Avenues

Remethylation Disorders Therapeutic Avenues


The current therapeutic objective is described in the Guidelines for the diagnosis and management of Remethylation Disorders. Click here to view the Guidelines.

There is currently one HCUNA-funded project for the treatment of Remethylation disorders being investigated. However, the majority of current research is focused on the natural history and improving diagnosis and treatment. The following are descriptions of potential avenues of research that have promise for novel therapeutics. See our Investigational Therapies Research Map.



Natural history studies are imperative in understanding the biochemical pathway for Remethylation disorders to aid in diagnosis and treatment. Following patients for an extended period of time, researchers analyze treatment protocols, clinical manifestations, and medication management to improve patients' quality of life. Here are two natural history studies that will help further the understanding of Remethylation Disorders.

  • Clinical and Basic Investigations of Methylmalonic Acidemia and Related Disorders.
    • Currently enrolling patients over age 2, the National Institute of Health is conducting a natural history study of remethylation disorders. More information here (ADD LINK FOR STUDY)


  • Longitudinal study of ultra-rare inherited metabolic and degenerative neurological diseases
    • Currently enrolling patients over 18 who live in Europe, this study has a larger focus area but includes remethylation disorders due to their ultra-rare status and degenerative neurological issues associated with the disorder.

Metabolic Pathway Modifications

The following research has been originally conducted for homocystinuria due to Cystathionine Beta Synthase Deficiency (Classical Homocystinuria), however, would also aid in the treatment of remethylation disorders.

Potential Treatment Pathways

Here is a schematic overview showing the biochemical pathway and how current therapeutic interventions address the biochemical or disease process.
