Informations about the disease

Clinical Comment

Metabolic disease with anosmia, cataract, early-onset retinitis pigmentosa, possible neurological manifestations as peripheral neuropathy, cerebellar ataxia, deafness; ichthyosis, skeletal abnormalities, cardiac arrhythmia; accumulation of phytanic acid in plasma + tissues

PEX7 mutations: rhizomelic chondrodysplasia punctata type 1, severe/often lethal, intellectual disability, rhizomelic shortening of the upper extremities, dwarfism, cataract. Mild variants -> Refsum disease
