First Claim
Patent Images
1. A method for determining a human'"'"'s capacity to metabolize a substrate of a CYP2C19 enzyme, said method comprising the steps of:
- a) isolating single stranded nucleic acids from the human, said nucleic acids encoding 5′
flanking regions of CYP2C19 genes present on each homologous chromosome 10 of the human, wherein said region is represented by a sequence as set forth in SEQ ID NO;
1; and
b) detecting at least two polymorphisms within the region, wherein the polymorphisms are nucleotides present at polymorphic sites represented by positions 352 and 1060 of SEQ ID NO;
1.
