FDA approves leucovorin for rare genetic condition, but not for autism

The FDA approved leucovorin as a treatment only for cerebral folate deficiency with receptor 1 gene mutations (affecting approximately one person per million), not autism. This approval contradicts earlier statements by officials who claimed the drug could benefit thousands of children on the autistic spectrum, leading to increased prescription demand and supply shortages despite fewer than 50 cases worldwide being identified globally for this specific condition.

The FDA announces the drug leucovorin may be used for cerebral folate deficiency, a rare neurological condition characterized by low levels of vitamin B9 in the brain.

The U.S. FDA approved high-dose vitamin B (leucovorin) for a rare genetic condition affecting approximately one in every million people worldwide and has identified fewer than fifty cases globally. This approval contradicts the September White House briefing where officials promoted leucovar as an effective treatment potential to thousands of children with autism, despite no evidence supporting such claims at that time or since then (the text cuts off before providing further details).
