Guidelines For Genetic Testing
Genetic testing is becoming more common and scientists are giving doctors guidelines on when it's appropriate in children.
Experts say DNA screening in newborns should be encouraged to look for treatable conditions like sickle-cell disease.
But they say kids should not be tested for genes that may affect them as adults.
The new policy recommends against girls being screened for the BRCA gene mutations that put women at a higher risk of breast and ovarian cancer.
