Target ValidationStrong
Frataxin deficiency drives mitochondrial iron-sulfur cluster failure in Friedreich ataxia; restoring expression is mechanistically grounded.

Translational assessment

1 claims

EndpointsLimited
mFARS is the accepted clinical endpoint; DRG-targeted dosing must balance frataxin restoration against overexpression toxicity.

AI brief

flag off · defaultPhase 7

Runtime AI features are flag-gated and disabled by default. Set SIGNAL_LLM_ENABLED=1 (plus a provider key) to enable a grounded, source-cited brief generated from this asset's structured records — with forbidden-phrase and grounding validators enforcing no probability-of-success or buy/sell language.

Evidence tiers and reviewer rubric scores are internal, qualitative inputs — [signal.] surfaces never show a numeric probability of success or buy/sell language.
