Perceptions of parents of children with hearing loss of genetic origin in South Africa.

More than 80% of people with hearing loss (HL) live in low- and middle-income countries. Up to 90% of deaf children are born to hearing parents, leading to novel parenting, communication, educational, and psychosocial experiences. Half of congenital pre-lingual HL is genetic, with a relatively high recurrence risk that may lead to specific challenges for parents of affected children. Currently, little is known of genes implicated and causative mutations for most populations who have HL in Sub-Saharan Africa, as well as genetic counseling services needs for this population. Therefore, this study aimed to explore parents' perceptions and understanding of the genetic etiology of their child's HL, in order to inform policies and services. In-depth qualitative interviews were conducted with 11 parents of children who have non-syndromic HL of putative genetic origin. Data were analyzed through the framework approach. Three salient themes emerged, namely comprehension and understanding of the cause, in which most parents were unable to identify the potential hereditary cause of their child's HL; responsibility and blame; and their perception of genetic counseling and testing. Most of the participants had positive attitudes towards genetic testing, describing that it may provide answers and that the information gained would be helpful for the future. The data could assist in understanding the challenges faced by parents, in the absence of genetic testing, emphasizing the need for accurate genetic testing to support counseling services to parents of children with HL in an African Setting.
