Abstract
Genetic testing holds great potential for preventing morbidities and mortalities for a number of diseases through early detection and effective intervention. As the number of genetic tests expand, so will public demand for these services. Therefore, it is essential to evaluate access to genetic testing and genetic services to ensure that all Canadians, including vulnerable groups, have equitable access to all forms of health care, in keeping with the mandate of the Canadian Health Act. The purpose of this paper is to examine the literature to determine if and how the Deaf community, as a vulnerable group, is at an increased risk of inequitable access to genetic services in Canada and to discuss how those who are deaf and hard of hearing are subject to the same risks. First, we define vulnerability and describe why the Deaf community, as a social group, can be considered a vulnerable group, followed by a description of the benefits of genetic testing. Second, we describe the barriers to accessing genetic testing, and how the d/Deaf and hard of hearing population experience additional barriers. Third, we examine the difficulties incorporating genetic testing into medical practice, and how this creates additional barriers to those already at risk. Finally, we discuss the steps necessary to promote equitable access to genetic testing among the d/Deaf and hard of hearing populations within Canada, and provide recommendations for further research in this topic area. Lastly, we comment on how barriers to genetic testing vary among the d/Deaf and hard of hearing is dependent upon the type of health care system available (whether public or private).
