Answer:
The issue most important for the IRB to consider is effects of findings on other family members.
Step-by-step explanation:
The Institutional Review Board (IRB) is an administrative board whose primary goal is to protect the rights and welfare of people who contribute to human research activities. The IRB is also concerned about maintaining the privacy of the human subjects. They have the right to approve or disapprove any human subject from participating in a research programme.
