DNA tests could reveal proof of incest

LONDON — Scientists conducting DNA tests on disabled children may inadvertently make startling discoveries of incest, sparking a range of ethical dilemmas that require guidance, doctors say.

In a letter to the medical journal Lancet published on Friday, Arthur Beaudet of Baylor College of Medicine in Houston and colleagues point out several thorny issues DNA experts may confront when performing genetic tests on children with developmental or intellectual problems.

Scientists sometimes analyze the DNA of disabled children looking for clues to understand their underlying disorders. That may lead to chromosomal information that identifies the children as having been conceived by two close relatives.

The authors say scientists doing such tests could legally be required to report that information to authorities in cases where the mother conceived as a minor.
