||Associated with Response to Non-Steroidal Anti-Inflammatory Drugs, see text of rs-page for discussion. Indicates poor histamine breakdown due to decreased DAO activity, compared to the CC allele.
rs10156191, also known as Thr16Met or T16M, represents a variant in the AOC gene on chromosome 7; this gene is also known as the DAO or diamine oxidase. The rs10156191(C) allele encodes the more common Thr amino acid at this position, and the (T) allele encodes the Met. The DAO Met allele is considered to encode a protein with lower metabolic capacity than the Thr allele.[PMID 21488903]
