At-home genetic testing in pediatrics.

Abstract

This review discusses the state of at-home genetic testing, including both direct-to-consumer and consumer-directed genetic testing, for children. At-home genetic testing continues to increase in popularity and laboratories are starting to offer tests geared towards newborns and children. Available at-home genetic tests for children address ancestral descent, supplement newborn screening, or provide risks for childhood and adult-onset disorders as well as pharmacogenomic data. However, there are aspects of at-home testing that are unique to children that both providers and parents need to be aware of before considering this type of testing; these include issues related to motivations for testing; privacy concerns; result interpretation; ethical, legal and social implications; and impact on family relationships, among others. This review addresses the challenges associated with at-home genetic testing in children and provides guidance for pediatricians and other health care providers who field inquiries about this type of testing or who are presented with at-home genetic test results for interpretation.
