Genetic screening: carriers and affected individuals.

Area of Science:

• Genetics
• Public Health
• Genomic Medicine

Background:

• Genetic screening identifies carriers and affected individuals using high-throughput analytical methods.
• Current genetic screening encompasses carrier, prenatal, and newborn screening.
• Newborn screening, with over 40 years of data, provides a model for broader genetic screening initiatives.

Purpose of the Study:

• To review the current landscape of genetic screening.
• To highlight policy considerations and lessons learned from newborn screening.
• To explore future directions in population-based genetic screening for adult-onset disorders.

Main Methods:

• Analysis of current genetic screening practices.
• Review of policy concerns in newborn screening.
• Discussion of future research needs for population-based screening.

Main Results:

• Newborn screening serves as a model for genetic screening, offering valuable experience and lessons.
• Policy considerations include disorder/technology selection and centralization of policy setting.
• Sharing experiences and developing databases are crucial for all genetic screening.

Conclusions:

• Future genetic screening will expand to adult-onset disorders, necessitating research into predictive risk across ethnocultural groups and effective interventions.
• Ethical considerations regarding screening timing and data usage must be addressed.
• Genomic medicine's potential for predictive, preventive, and personalized healthcare relies on resolving these challenges.
