We detected a point mutation in the transthyretin (TTR) gene in a patient with familial cardiac amyloidosis by using PCR-DCP (DNA conformation polymorphism) analysis that is based on the diversity in electrophoretic mobility of single-stranded DNAs and/or heteroduplex DNAs in PCR products. The PCR products of the transthyretin gene were denatured in the presence of formamide and electrophoresed in a non-denaturing polyacrylamide gel to detect an electrophoretic change due to a sequence variation. An unusual DNA fragment was visualized by silver staining in the PCR products of the exon 3 from the patient. Subsequent sequencing analysis revealed a T to A transversion and led to a replacement of Serby Ile at codon 50 of the TTR gene.
