The [[rs72558186]](A) SNP represents a [[CYP2C19]] allele known as CYP2C19*7; it reflects a splice donor mutation that leads to a poor metabolizer phenotype.{{PMID|10411572}}

This SNP is also known as CYP2C19_19294T>A, and in the Affymetrix DMET panel, as DMET3B10072.

Note: absence of allele frequency data leaves this as a possible ambiguous flip.
