Deafness, Autosomal Recessive 91, also known as dfnb91, is related to sensorineural hearing loss and deafness, autosomal dominant 17. An important gene associated with Deafness, Autosomal Recessive 91 is SERPINB6 (Serpin Family B Member 6), and among its related pathways/superpathways are G-protein signaling G-Protein alpha-i signaling cascades and Myometrial relaxation and contraction pathways. Related phenotypes are progressive hearing impairment and nervous system
