| Description: |
As a model for the detection of human genetic disease in preimplantation embryos, we describe a method in which trophectoderm biopsy samples from viable mouse blastocysts are simultaneously analyzed for the presence of a normal or mutant allele of the myelin basic protein gene by the polymerase chain reaction. The biopsied embryos are kept in culture during analysis of biopsied material and later reintroduced to a foster mother. Prenatal diagnosis can be completed in less than 7 hr. The identity of either amplification product was proved conclusively by direct sequence analysis of amplified products. Ninety-six percent of recovered blastocysts survived biopsy, as judged by re-formation of a blastocyst cavity in culture. Fifty-nine percent of the biopsied embryos established pregnancy by day 6.5, compared to 88% of unmanipulated controls. This approach can be applied to preimplantation diagnosis of human genetic diseases by using extraembryonic cells from blastocysts obtained after in vitro fertilization or uterine lavage. It will make possible the elimination of a mutant allele from a family in a single generation. ; © 1990 National Academy of Sciences. Contributed by Leroy E. Hood, March 19, 1990.
