Parental Request for BRCA1 Testing in a 9-Year-Old
The parents of a 9-year-old girl request BRCA1 testing because the girl's mother carries a pathogenic BRCA1 variant and the mother's sister died of ovarian cancer at 44. The parents say they want to 'prepare her' and start breast surveillance early; they also worry about a future insurer. The girl is healthy, has no breast symptoms, and says she does not really understand what the test is. The family is private-pay; the laboratory will accept a pediatric sample with parental consent. The counselor works in a pediatric genetics clinic and has one visit. The mother is already under high-risk surveillance. The father supports testing, and both parents say they will not tell the child the result until she is older if positive.
1. Should the clinic offer BRCA1 predictive testing to the 9-year-old?
Read the worked answer
No, not as a routine clinical test. BRCA1 is an adult-onset predisposition gene, and there is no proven childhood intervention that changes outcome. Breast surveillance and risk-reducing surgery are not recommended in childhood, and the psychosocial and insurance risks of knowing a result at age 9 are real. Professional guidance supports deferring predictive testing for adult-onset conditions until the person can decide for herself, usually at 18 or older, unless there is a childhood-actionable condition. The parents' anxiety is understandable, especially after the sister's death, but testing the child would not provide useful medical management now. Explain that the mother's mutation is already known, so the child's risk can be discussed without testing. Offer genetic counseling for the parents, a plan to revisit testing when the daughter is older, and resources about hereditary breast and ovarian cancer. Do not order the test simply because a laboratory will accept the sample.
2. How should the counselor respond to the parents' plan to conceal a positive result until the child is older?
Read the worked answer
Use the plan as a reason to pause, not as a neutral detail. A genetic result belongs to the child and becomes part of her medical record. Concealing it from her while parents know it can distort family communication and make later disclosure feel like a betrayal; it also creates practical problems if the child needs medical care or accesses records. Ask what the parents fear the child would feel and what they hope early knowledge would achieve. Explain that a child's understanding develops over time and that disclosure should be paced, but secrecy is different from age-appropriate explanation. If testing were clinically indicated, the child's assent and a plan for gradual disclosure would be essential. Here, because testing is not indicated, the counselor can say that not testing avoids the concealment problem altogether. Offer to meet again as the daughter approaches adolescence and to help the parents prepare for future conversations. Document the discussion.
3. The parents insist and say they will order a direct-to-consumer test instead. What should the counselor do?
Read the worked answer
Do not simply end the conversation. Acknowledge their worry and explain the limitations of direct-to-consumer testing for a known familial BRCA1 variant: the specific variant may not be included, raw-data interpretation can be inaccurate, and results may not be clinically confirmed. If they proceed anyway, they may create unverified information that affects the child's care and insurance. Offer a second counseling visit, a letter summarizing the recommendation, and a referral to a hereditary cancer program for the parents. Explore whether the parents are feeling pressured by the sister's death or by other relatives, and address grief and risk perception. Document that testing was recommended against and that the family was informed of the risks of going elsewhere. Keep the door open for the daughter to return at 18 for autonomous testing. If the parents are making a decision that could harm the child, follow institutional ethics and child-protection procedures as appropriate, but avoid coercion.
