A 5-base deleted mutation of adenomatous polyposis coli (APC) gene was detected by using electrospray ionization mass spectrometry of polymerase chain reaction (PCR) products. Genomic DNA was extracted from a familial adenomatous polyposis patient blood, and a 57-base pairs segment of APC gene was amplified by PCR. The PCR products were purified, digested with restriction endonuclease, purified, and determined by electrospray mass spectrometry.
