Predictive genetic testing for conditions that present in childhood

Area of Science:

• Medical Ethics
• Pediatric Genetics
• Public Health Policy

Background:

• Consensus exists against predictive genetic testing for late-onset conditions in children.
• Limited ethical consideration has been given to testing asymptomatic children for disorders presenting later in childhood, especially when presymptomatic treatment is ineffective.
• This paper addresses the ethical implications of predictive genetic testing and screening in young children for conditions manifesting later in childhood.

Purpose of the Study:

• To examine the ethical considerations of predictive genetic testing and screening for childhood-onset disorders in newborns and young children.
• To analyze the risks and benefits associated with different scenarios of predictive genetic testing and screening.
• To inform ethical guidelines regarding genetic testing in pediatric populations.

Main Methods:

• Ethical analysis of predictive genetic testing scenarios.
• Review of risks and benefits for (1) high-risk families, (2) untreatable conditions, and (3) conditions with equivocal presymptomatic treatment efficacy.
• Consideration of parental discretion versus state-sponsored screening.

Main Results:

• Ethical arguments are presented for and against predictive testing and screening in children.
• Distinctions are made based on the nature of the condition (treatable vs. untreatable) and the context of testing (family vs. population screening).
• The efficacy of presymptomatic treatment significantly influences the ethical calculus.

Conclusions:

• Parental discretion should be respected for predictive genetic testing in children.
• State-sponsored predictive screening is not ethically supported for conditions that do not meet established public health screening criteria.
• Ethical frameworks must balance individual autonomy, potential harms, and societal benefits in pediatric genetic testing.
