Abstract
In a Muslim Israeli Arab village, different types of hearing loss affect some 2% of the inhabitants. Most cases of profound deafness are due to recessive mutations in the Connexin-26 gene. Since in this community, marriages are by preference within the family (consanguineous), for many of the couples from the village the risk for an affected child is high. There are 30 families living in the village in which both parents have normal hearing and at least one child has a profound hearing defect. In these families, the birth of a child with profound deafness did not change family planning. The rate of marriage was similar for the siblings of deaf children as for other individuals in the village. The major problems were encountered by the deaf individuals themselves; in particular, most of the women were not married. Because of the distinctive nature of this particular problem, different types of screening programs were envisaged. However, all of them are problematic. Therefore, as a first step it was decided to begin a program including individual genetic counseling together with education of the entire population on practical aspects of human genetics.
