Description : Chaib et al. (1996) reviewed the frequency and inheritance of congenital isolated
deafness and causes for difficulties associated with mapping of deafness genes. They
noted that in the U.S., deafness affects 1 in 1000 children at birth or during infancy.
About 75% of the inherited forms of congenital isolated deafness have an autosomal
recessive mode of transmission.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the cadherin 23 gene (CDH23, 605516.0005);
