초록

We have identified and analyzed the 5'-coding region of SCN5A gene in Korean genome. Although its sequence has already been reported in western countries it is still important to confirm our own sequence for the establishment of Korean-suitable diagnosis on genetic basis. Total RNAs were obtained from three healthy Korean adult hearts and reversely transcribed. RT products were then subjected to PCR reaction followed by DNA sequencing. Three different sets of SCN5A primers were designed and used for the amplification of 5'-coding region of SCN5A from Korean genome. Amplified sequence was roughly one-10th of the entire SCN5A mRNA in size and its detailed sequence was completely matched up to the previously reported sequence. There was no difference between three heart samples, either. So, SCN5A was concluded as the relatively stable gene comparing to other genes that are involved in long QT syndrome.
