Abstract

Abstract : Bjornstad syndrome is a rare condition characterized by pili torti and sensorineural hearing loss associated with pathological variations in BCS1L . Mutations in this gene are also associated with the more severe complex III deficiency and GRACILE syndrome. We report the first Italian patients with Bjornstad syndrome, two siblings with pili torti and sensorineural hearing loss, in whom we detected two novel compound heterozygous mutations in BCS1L . A thorough clinical evaluation did not reveal any features consistent with complex III deficiency or GRACILE syndrome.
