There are no age limits on genetic testing. However, we do not recommend predictive genetic testing (e.g., BRCA 1/2) for children unless advised by your physician. Children should be given the right to make a decision about whether they want to find out their risks and illness susceptibility when they come of age. Many genetic illnesses have no known cure, and knowing too much may have impacts on their life choices. If possible, delay discussions about genetic testing until the child comes of age.
