CHICAGO -- The American College of Obstetricians and Gynecologists is preparing to announce recommendations that are expected to widen the scope of who should be offered carrier screening for cystic fibrosis, Dr. Michael Mennuti, ACOG secretary, told this newspaper.
The ACOG recommendations are being developed in response to a 1997 National Institutes of Health recommendation that all couples planning a pregnancy or seeking prenatal care be offered CF screening.
Currently, ACOG recommends that physicians offer screening to couples with a family history of CF and to reproductive partners of women with the disease.
Over the past few years ACOG and other professional groups have been working together to refine the NIH recommendations and to develop guidelines and educational materials needed to implement them. Dr. Mennuti, professor of ob.gyn., human genetics, and pediatrics at the University of Pennsylvania, Philadelphia, cochaired a steering committee that spearheaded these efforts.
The American College of Medical Genetics has just released laboratory guidelines for a screening test that would identify 25 of the most common CF mutations. This would allow for a CF carrier detection rate of 85%-90%, Dr. Francis Collins, director of the Human Genome Project at NIH in Bethesda, Md., said during ACOG's recent annual meeting in Chicago.
Population-based CF carrier screening "is a good example of how the revolution in molecular genetics is making its way to the clinic," he added.
"Most people will be tested, and they will be negative. But when a test is positive for one member of the couple, but not the other, this may create some anxiety. Although this would mean a very low risk of having an affected child, it would not mean a zero risk because there is the slight chance that the ...
