Fatty acid hydroxylase-associated neurodegeneration (FAHN) is a very rare, autosomal recessive form of neurodegeneration with brain iron accumulation (NBIA) characterized by childhood-onset focal dystonia, progressive spastic paraplegia that progresses to tetra paresis, ataxia, dysarthria, intellectual decline, and oculomotor disturbances (optic atrophy), accompanied by iron deposition in the globus pallidus.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
1 clinical trial registered, 1 recruiting. Interventions under study include other interventions. Research is primarily sponsored by academic and government institutions.
4 publications have been identified in PubMed for fatty acid hydroxylase-associated neurodegeneration. Research spans Review / Meta-Analysis (50%), Other (25%), and Basic Science / Preclinical (25%).
