Located at highly conserved areas, primers CYP779f and Tena32F, by contrast, were able to unequivocally amplify fragments that cover the entire length of the CYP21 genes and its 2-sided flanking sequence at the centromeric tail of the RCCX module, thus accurately identifying different types of chimeric CYP21A1P/CYP21A2 genes.
