Non-Syndromic Genetic Deafness, also known as nonsyndromic genetic hearing loss, is related to deafness, autosomal recessive 1a and sensorineural hearing loss. An important gene associated with Non-Syndromic Genetic Deafness is CDH23 (Cadherin Related 23), and among its related pathways/superpathways are Olfactory Signaling Pathway and RhoGDI Pathway. Affiliated tissues include monocytes and bone, and related phenotypes are delayed speech and language development and progressive sensorineural hearing impairment
