An article was published in the journal Lancet on February 11, 2011 about the exposure of incest cases from genetic tests. Researchers at Baylor College of Medicine in Houston have been studying child birth defects and developmental delays, and have been performing a new type of genetic test, called single nucleotide polymorphism-based arrays, to plot out a person's genetic makeup. The tests enable them to locate missing or duplicated genes by mapping out a child's genetic code. Often, the inconsistencies found in these tests can explain the child's disability. In several cases, however, scientists found large, duplicate pieces of DNA believed to be inherited from an inappropraite relationship between two relatives. The main concern that stems from this discovery is the possibility of evidence of child sexual abuse, most often girls between ages twelve and sixteen. Doctors now have routine tests to check if a child's disability is caused by incest. If a case does involve incest, doctors are obligated to tell authorities about cases of suspected child abuse.
This discovery of incest cases from new genetic tests has left teams of researchers with an abundance of legal and ethical questions. Dr. Arthur Beaudet, chairman of molecular and human genetics at Baylor, says, "The concern mainly stems from the possibility of children being sexually abused in the home." I think this discovery could turn out to be extremely helpful in court cases of child sexual abuse where no other evidence is available. It may expose some dark family secrets, but it may also provide closure for the victims of this type of abuse. What do you think?
This post kind of made me sick, yet it was very interesting! It's amazing that they can tell if a child was abused due to their genetic makeup. Although it is a private matter, I feel that the doctors have the right to go to the authorities. Nobody wants to see children hurt.
