Summary

Parents of deaf children show high interest in genetic testing for deafness, but lack understanding of genetics. Genetic counseling is crucial for effective use of this technology.

Area of Science:

  • Genetics
  • Audiology
  • Medical Genetics

Background:

  • Genetic testing for deafness is now available due to molecular advances.
  • Limited data exists on interest in genetic testing among deaf individuals and families.
  • Most deaf children (90-95%) are born to hearing parents, making them a key demographic.

Purpose of the Study:

  • To assess the attitudes of hearing parents with deaf children towards diagnostic, carrier, and prenatal genetic testing for deafness.
  • To evaluate parental understanding of genetic inheritance and recurrence risks.
  • To determine the need for genetic counseling alongside genetic testing.

Main Methods:

  • A survey was distributed to 328 hearing parents with at least one deaf child.
  • 96 surveys were completed and returned for analysis.

  • Attitudes toward genetic testing and understanding of genetic concepts were assessed.

    • Main Results:

    • 96% of respondents expressed positive attitudes toward genetic testing for deafness, including prenatal testing.
    • None of the respondents indicated they would terminate a pregnancy based on test results.
    • All parents demonstrated a poor understanding of genetics, with 98% misinterpreting recurrence risks and inheritance patterns.
    • No significant difference in understanding was observed between parents who had undergone testing and those who had not, suggesting potential issues with genetic counseling.

    Conclusions:

    • Hearing parents of deaf children are highly interested in genetic testing for deafness.
    • Genetic testing for deafness should be accompanied by formal genetic counseling to ensure proper understanding of risks, benefits, and limitations.
    • Effective genetic counseling is essential for informed decision-making regarding genetic testing in this population.
