Attitudes to genetic testing for deafness: the importance of informed choice

With recent progress in the identification of genes for deafness, it is highly likely that genetic testing, including pre-natal testing, for deafness will become more widely available. In a context where there are concerns about pre-natal testing, and where many in the Deaf community contest the understanding of deafness as a disability, it is important to examine the attitudes of Deaf/deaf people toward genetic testing. This qualitative study employed in-depth interviews to investigate the views about genetic testing for deafness of 19 participants, who were identified as functionally deaf or hearing impaired, or as belonging to the Deaf community. The key findings are that participants were generally supportive of genetic testing for deafness but only when full information about all relevant aspects of deafness is given to prospective users of genetics services. Participants emphasized informed choice, stating that information about medical and technological options for deaf people should be provided, together with information about communication, education, and the experience of being deaf. Although there was less support for pre-natal diagnosis and termination of pregnancy for deafness, most participants nonetheless felt that individual choice was important and that pre-natal diagnosis should be made available to those who wanted to use it.
