Converting diploidy to haploidy for genetic diagnosis |
摘要 |
Detection of mutations associated with hereditary diseases is complicated by the diploid nature of human cells. Mutations present in one allele are often masked by the wild-type sequence of the other allele. Individual alleles can be isolated from every chromosome within somatic cell hybrids generated from a single fusion. Nucleic acids from the hybrids can be analyzed for mutations in an unambiguous manner. This approach was used to detect two cancer-causing mutations that had previously defied genetic diagnosis. One of the families studied, Warthin Family G, was the first kindred with a hereditary colon cancer syndrome described in the biomedical literature.
