November SNPits Summary

The November issue of UF Health Personalized Medicine Program's e-newsletter, SNPits, is out.  This issue contains a summary of a recent paper by Nicholson and Formea in Clinical Chemistry that discusses implementing CPIC guidelines for CYP2D6 and codeine.  The authors highlight some of the difficulties that may arise in the clinic.  We are pleased that the larger clinical community is beginning to embrace PGx guidelines and practice.

PharmGKB VIP Summary for CYP4F2 published in Pharmacogenetics and Genomics

The PharmGKB Very Important Pharmacogene (VIP) summary describing important pharmacogenetic variants in CYP4F2 was recently published by Pharmacogenetics & Genomics. Cytochrome p450, family 2, subfamily F, polypeptide 2 (CYP4F2) catalyzes the oxidation of the terminal carbon of the side chains of vitamin K, vitamin E, arachidonic acid (AA), and leukotriene B4 (LTB 4). Thus, CYP4F2 plays a role in the regulation of the inflammation response, blood pressure as well as vitamin K and vitamin E bioavailability. A single genetic variant (rs2108622 C>T also known as CYP4F2 *3) has consistently demonstrated a small but significant effect on warfarin and acenocoumarol dosage and safety, particularly in Caucasian and Asian populations.
