Abstract: | The results of a genetic epidemiological study of hereditary deafness (HD) in ten raions (districts) of Kirov oblast (administrative
region), Russia, are presented. A total of 122 075 people have been examined. Segregation analysis of all families with diagnosed
HD has demonstrated a good fit to either the autosomal dominant (AD) or autosomal recessive (AR) mode of inheritance. The
total prevalence rates of AD and AR HDs, as well as the specific prevalence rates of nonsyndromic and syndromic forms of HD,
have been calculated for the population of ten raions. The HD prevalence rate in Kirov oblast has been found to be 1: 1043
people (1: 1453 and 1: 3699 for the nonsyndromic and syndromic forms, respectively). This value has been found to vary in
different raions, which is explained by differences in the genetic subdivision levels of the populations studied; the correlation
coefficient between the HD load and random inbreeding (F
ST) in district populations is r = 0.81 ± 0.22. The diversity of syndromic hearing disorders is described. |
