This study addressed the question of whether a hearing loss caused by mutations in the connexin 26 gene had a significant effect on language and speech perception outcomes in children using cochlear implants or hearing aids. The families of children who had participated in two previous studies of language development were invited to participate in this genetic study. From the 52 children whose families agreed to participate, 15 children with connexin 26 mutations in both chromosomes were identified. After taking into account other factors which are known to affect language development and speech perception in children with impaired hearing, no significant differences were found between the 1..
