[Genetic characteristics of recessive sensorineural hearing loss].
Genetic characteristics of recessive sensorineural hearing impairment mediated by 5 recessive genes were studied. One of these is responsible for early progressive hearing loss, others causing congenital deafness. The incidence of early progressive recessive hearing loss in a population is 1:20,000, gene frequency being 0.007; the incidence of heterozygotes for this gene is 1.4%. The incidence of each of 4 forms of recessive congenital hearing loss in a population is 1.125:10,000, the frequency of these genes being 0.0106; the incidence of heterozygotes for each of these genes is 2.1%. The total frequency of all recessive genes for sensorineural hearing impairment is 0.0494 and the incidence of heterozygotes for all genes is 9.9%. The frequency of different genotypes for recessive genes specifying sensorineural hearing loss was established, based on the data obtained.
