✦ Synopsis

A mutation analysis method based upon a wild-type DNA sequence is presented. Oligonucleotides were utilized for primer extension by T7 DNA polymerase to discriminate between wild-type and mutant sequences in two solid phase approaches. 1. Oligonucleotides were annealed to an immobilized template, extended with fluorescent dideoxynucleotides (ddNTPs), and analyzed on an automated fluorescent DNA sequencer. The oligonucleotide length identified the known mutation site, and the fluorescence emission of the ddNTP identified the mutation. 2. Template DNA was annealed to an oligonucleotide array, extended with CY-~'P dNTPs, and analyzed with a Phosphor Imager. The grid position of the oligonucleotide identified the mutation site and the extended base identified the mutation. 0 1 9 % WiIey-Lus, Inc.
