PATENT CLAIMS Method of diagnosing patient having deficiency in S-mephen
ytoin 4'-hydroxylase activity
- Obtaining sample of nucleic acid from patient
- Analyzing a cytochrome P450 2C19 DNA seq from the
nucleic acids in sample for presence of polymorphism indi
cative of the deficiency
- Wherein the polymorphism occurs at nucleotide 681 or 636
of the coding region of the P450 2C19 DNA genomic or
cDNA seq
- Wherein each nucleotide in coding region of the genomic
seq is designated the same number as the corresponding
nucleotide in the coding region of the cDNA seq in FIG 2,
clone 11a (SEQ ID NO:2) when the genomic seq & cDNA
seq are maximally aligned & the nucleotides in the coding
region of the cDNA seq are assigned successive numbers
starting of 1 for the A residue of the initiating methionine co
