Comment

Polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and cataract (PHARC) is a neurodegenerative disease. Patients present early-onset cataract and hearing loss, retinitis pigmentosa. Both the central and peripheral nervous systems are affected. Other features are demyelinating sensorimotor polyneuropathy and cerebellar ataxia. Fiskerstrand et al. identified the disease in a norwegian family. Mutations in ABHD12 cause the PHARC. Polyneuropathy and ataxia can be mild and symptomes can be close to those of Usher syndrome type 3 as shown by Eisenberg et al.
