Area of Science:

• Genetics
• Pediatrics
• Medical Sociology

Background:

• Genetic testing is increasingly used for deaf infants and children.
• Understanding parental perspectives on genetic testing is crucial for effective counseling.

Purpose of the Study:

• To examine parental reasons for and beliefs about genetic testing for deafness.
• To determine if these reasons and beliefs differ across ethnic groups.

Main Methods:

• Baseline data from 56 Caucasian, 59 Hispanic, and 24 Asian parents of deaf children were analyzed.
• A longitudinal, prospective study focused on genetic testing for connexin-related deafness.

Main Results:

• Reasons for and beliefs about genetic testing for deafness varied significantly by ethnicity.
• Asian and Hispanic parents were more likely than Caucasian parents to cite family planning, child's medical care, and family benefits.
• Asian and Hispanic parents were also more likely to perceive potential harm from genetic testing.

Conclusions:

• Genetic testing satisfies parents' need to understand the cause of their child's deafness.
• Ethnic differences suggest varied motivations, including family planning and medical care, for pursuing genetic testing.
• Acknowledging diverse parental perspectives enhances genetic counselors' cultural competence and improves pre-test counseling.
