tokens: The two polymorphisms were localized in noncoding part of the gene 1 ) a C / G polymorphism in the promotor region , 142 bp upstream from the transcriptional initiation site ( - 142C / G ) , and 2 ) a 6 bp deletion polymorphism in the 3 noncoding part of the CPO gene , 574 bp downstream of the last base of the normal termination codon ( + 574 delATTCTT ) .
