title: [Genetic screening among children with congenital and early childhood hearing loss].
abstract: Prevalence of mutations of genes of connexin 26, connexin 30 and mitochondrial DNA was studied among children with congenital and early childhood hearing loss. Screening with available methods of DNA diagnosis was conducted in some specialized schools. It was found that genetic disorders among children with congenital and early childhood hearing loss are rather frequent. Genetic consulting of parents with normal hearing carrying abnormal gene can help avoid birth of deaf children.
