Genetic testing for hearing loss: different motivations for the same outcome

Area of Science:

• Genetics
• Audiology
• Medical Sociology

Background:

• Recent genetic discoveries offer new avenues for families affected by hearing loss.
• Understanding parental perspectives on genetic testing is crucial for effective implementation.

Purpose of the Study:

• To assess the interest and motivations of parents of children with hearing loss regarding genetic testing and prenatal diagnosis.
• To explore how cultural and religious beliefs influence decisions about genetic testing for deafness.

Main Methods:

• A questionnaire survey was administered to 139 parents of deaf and hard-of-hearing children in Israel.
• The survey evaluated parental intentions, reasons for opting in or out of genetic testing, and prenatal diagnosis.

Main Results:

• A high interest (87%) in genetic testing was observed among Israeli Jewish parents, irrespective of religious affiliation.
• Motivations for genetic testing varied significantly across religious sectors, with ultraorthodox parents prioritizing matchmaking over family planning.
• A universal desire to understand the cause of hearing loss was reported across all religious groups.

Conclusions:

• Genetic testing for hearing loss is broadly welcomed across diverse communities, including those not typically engaging in genetic counseling.
• Culturally sensitive approaches are essential to maximize the benefits of genetic testing and counseling for all populations.
• Tailoring genetic services to specific cultural norms and beliefs can enhance uptake and acceptance.
