New PharmGKB pathway: Paroxetine

The paroxetine PK pathway is the newest addition to PharmGKB's pathway summaries. Paroxetine is a selective serotonin reuptake inhibitor (SSRI) used for the treatment of multiple psychiatric disorders including mood, panic, anxiety, and obsessive compulsive disorders. The pathway diagram depicts candidate genes mediating the transformation of paroxetine into

New PharmGKB VIP Summary: HLA-B

Human leukocyte antigen B (HLA-B) is a cell-surface molecule responsible for the presentation of endogenous peptides to cytotoxic CD8+ T cells. This presentation of peptides allows for the recognition of pathogens, and leads to an immune reaction that destroys the infected cell. Variations within the HLA-B gene affect which peptides

European approval of additional CFTR variants listed for ivacaftor use

The drug Ivacaftor (Kalydeco) was originally indicated for use in cystic fibrosis (CF) patients with one or two copies of the G551D variant (rs75527207) in the CFTR gene. The European Commission has approved the use of ivacaftor in patients with an expanded list of CFTR variants that all result in

Praise for PharmGKB

PharmGKB is “the Holy Grail” for DNA STAT, a company that provides pharmacogenomics testing for patients. DNA STAT goes on to praise PharmGKB’s “accessibility and comprehensiveness” and highlights its “interactive SNP features and tools for education and clinical implementation of genetic data.”

Ifosfamide PK and PD pathways published in PG&G

Ifosfamide is a produg used in combination chemotherapy for the treatment of solid tumors. Around 20% of patients experience toxicity. Pathways depicting the genes involved in the pharmacokinetics and pharmacodynamics of ifosfamide have been published in PG&G. Variants in these genes that are associated with toxicity and drug

New PharmGKB VIP Summary: CYP4F2

Cytochrome p450, family 2, subfamily F, polypeptide 2 (CYP4F2) is known to catalyze multiple biological reactions. It is predominantly expressed in the liver and kidneys, although there is evidence that it is also expressed in the intestines. Of specific interest in pharmacogenetics, hepatic CYP4F2 regulates the bioavailability of vitamin K

Introducing CFTR as a Very Important Pharmacogene (VIP)

Variants within the CFTR gene underlie Cystic Fibrosis (CF). Traditionally, drugs used in the treatment of this disease have focused on ameliorating symptoms, fighting infection, thinning mucus and dampening inflammation. Now, drug development is focusing on pharmaceuticals that correct the underlying CFTR defect. The PharmGKB CFTR VIP summary describes potential

CPIC simvastatin & SLCO1B1 guideline 2014 update published

The 2014 update of CPIC guideline regarding SLCO1B1 and simvastatin-induced myopathy, has been published in Clinical Pharmacology and Therapeutics. CPIC extensively reviewed the literature from February 2011 to December 2013 and concluded that the dosing recommendations provided in the 2012 CPIC guideline for SLCO1B1 and simvastatin-induced myopathy have not changed.

New publication: PharmGKB Uric acid-lowering drugs pathway

Disorders involving uric acid levels are prevalent (e.g. gout, hyperuricemia and resultant kidney failure) and pharmaceuticals that reduce the generation, increase the removal or prevent the absorption of uric acid have been developed to treat these disorders. Two PharmGKB pathways depicting the mechanism of action of these drugs and
