Common Name

Remarks

Donor subject has a single bp (G-to-A) mutation in exon 5 of the CYP2C19 gene (CYP2C19*2) which creates an aberrant splice site. The change altered the reading frame of the mRNA starting with amino acid 215 and produced a premature stop codon 20 amino acids downstream, resulting in a truncated, nonfunctional protein. Because of the aberrant splice site, a 40-bp deletion occurred at the beginning of exon 5 (from bp 643 to bp 682), resulting in deletion of amino acids 215 to 227. The truncated protein had 234 amino acids and would be catalytically inactive because it lacked the heme-binding region.

Identified Mutation

21158G>A ; The principal defect in CYP2C19 responsible for the S-mephenytoin poor metabolizer phenotype was found by de Morais et al. (1994) to be a single bp (G-to-A) mutation in exon 5 which creates an aberrant splice site. The change altered the reading frame of the mRNA starting with amino acid 215 and produced a premature stop codon 20 amino acids downstream, resulting in a truncated, nonfunctional protein. De Morais et al. (1994) demonstrated that 7/10 Caucasian and 10/17 Japanese poor metabolizers were homozygous for this defect. The inheritance of the deficient allele was found to be concordant with that of the PM trait. To determine the nature of the defect, since the genomic sequence of CYP2C19 was not yet known, de Morais et al. (1994) developed primers for the intron 4/exon 5 junction empirically. This involved the use of multiple primers for intron 4 based on the sequence of this region in CYP2C9, a closely related gene that shows 95% similarity to CYP2C19 in the upstream region and several exons, and a specific reverse primer for exon 5 of CYP2C19. Because of the aberrant splice site, a 40-bp deletion occurred at the beginning of exon 5 (from bp 643 to bp 682), resulting in deletion of amino acids 215 to 227. The truncated protein had 234 amino acids and would be catalytically inactive because it lacked the heme-binding region. De Morais et al. (1994) developed a simple PCR-based test for the defective CYP2C19 allele.
