I don't believe it is unethical to reveal a predisposition for a certain disease after sequencing a patient's genome, especially as new research identifies the effects of more mutations. Finding a disease early is often a critical factor in how well it can be treated, and what better way to do that than going straight to the source? This is a revolutionary new way to practice medicine, and I hope I will experience it first hand when I start seeing my own patients!
it is unethical only if the patient hasn't consent to be informed. Prior to any DNA sequencing, there should have been a consent process that clearly spell out the various scenarios of what the patient wants to be informed about.
