The individual, the family, and genetic testing

Area of Science:

• Medical Genetics
• Psychological Impact of Genetic Testing

Background:

• Healthcare providers often lack understanding of basic genetic principles and genetic testing science.
• The psychological effects of genetic testing are debated, particularly for newly emerged predictive tests.
• Understanding genetic testing is crucial for individuals, families, and healthcare professionals.

Purpose of the Study:

• To review literature on genetic testing and its implications for individuals and families.
• To examine issues related to genetic testing for adult-onset cancers using Huntington disease as a model.
• To explore responses to genetic susceptibility and implications of testing children.

Main Methods:

• Literature review of selected studies on genetic testing.
• Analysis of psychological effects and family responses to genetic disease diagnosis.
• Case study approach using Huntington disease for adult-onset cancer genetic testing issues.

Main Results:

• Limited empirical data exists on the psychological effects of newly emerged predictive genetic tests.
• Genetic testing for adult-onset cancers presents complex implications for individuals and families.
• Responses to genetic susceptibility and testing children require further investigation.

Conclusions:

• Enhanced understanding of genetic testing science is necessary for healthcare providers.
• Further research is needed on the psychological and familial impact of genetic testing, especially for adult-onset cancers.
• Identifying emerging issues in genetic screening can guide future nursing research in this area.
