The rapid molecular genetic diagnosis of cystic fibrosis by polymerase chain reaction: an experience report.

ABSTRACT

The authors report their experience with about two thousand DNA amplifications by polymerase chain reaction (PCR) in prenatal diagnosis of cystic fibrosis. The method is demonstrated on examples of diagnostic informativity and prenatal diagnosis examination in a family at 1 in 4 risk of the disease using closely CF-linked diagnostic polymorphisms J3.11/MspI, MetH/MspI, CS7/HhaI, KM19/PstI, Mp6-d9/MspI and XV2c/TaqI, PCR methodology and safety precautions are discussed.
