Clinical Information
讨论与实验室测试有关的生理学,病理生理学和一般临床方面

The most common adverse drug reaction associated with statins is skeletal muscle toxicity, which can include myalgia (with and without elevated creatine kinase levels), muscle weakness, muscle cramps, myositis, and rhabdomyolysis.(1) Rhabdomyolysis, while rare, is of clinical concern because of the risk for death as a result of cardiac arrhythmia, renal failure, and disseminated intravascular coagulation. While the underlying causes of statin-associated myopathy are not known, several hypotheses have been formulated, including those related to the biochemical pathway of cholesterol synthesis inhibition and statin metabolism.

SLCO1B1encodes the organic anion-transporting polypeptide 1B1 (OATP1B1) influx transporter located on the basolateral membrane of hepatocytes. OATP1B1 facilitates the hepatic uptake of statins as well as other endogenous compounds (eg, bilirubin). Changes in the activity of this transporter (eg, through genetic variations or drug-drug interactions) can increase the severity of statin-associated myopathy (ie, statin intolerance).(2)

SLCO1B1rs4149056 (c.521T>C, p.V174A), which is found in *5, *15, and *17,interferes with localization of the transporter to the plasma membrane and can lead to increased systemic statin concentrations.(3-4)All statins are substrates of OATP1B1, but the association ofSLCO1B1c.521T>Cwith statin intolerance varies depending on statin and dose and is most pronounced with higher doses of simvastatin therapy. A case-control study of simvastatin-induced myopathy observed an odds ratio (OR) for myopathy of 4.5 for *5 heterozygotes and 16.9 for *5 homozygotes (compared to individuals who did not carry *5) among patients receiving high-dose (80 mg/day) simvastatin therapy.(4) A dose relationship was also demonstrated in a replication cohort of patients taking 40 mg/day simvastatin with a relative risk of 2.6 per copy of the *5 allele. While theSLCO1B1c.521T>C genotype has also been shown to affect systemic exposure of other statins (eg, atorvastatin, pravastatin, rosuvastatin) in addition to simvastatin,(3) there is less evidence demonstrating a clinical association between theSLCO1B1genotype and myopathy with statins other than simvastatin.(2)

SLCO1B1rs4149015 (c.-910G>A), which is found in *17 and *21, is associated with increased pravastatin blood levels and a reduced lipid lowering effect but has not been associated with statin-induced myopathy or rhabdomyolysis.

Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Rare variants may be present that could lead to false-negative or false-positive results. If results obtained do not match the clinical findings (phenotype), additional testing should be considered.

Samples may contain donor DNA if obtained from patients who received non-leukoreduced blood transfusions or allogeneic hematopoietic stem cell transplantation. Results from samples obtained under these circumstances may not accurately reflect the recipient's genotype. For individuals who have received blood transfusions, the genotype usually reverts to that of the recipient within 6 weeks. For individuals who have received allogeneic hematopoietic stem cell transplantation, a pretransplant DNA specimen is recommended for testing.SLCO1B1genetic test results in patients who have undergone liver transplantation may not accurately reflect the patient'sSLCO1B1status.

Simvastatin-related myopathy can occur in the absence ofSLCO1B1c.521T>C.

存在SLCO1B1c.521T>C does not confer absolute risk for simvastatin-associated myopathy.

Absence of a variant allele does not rule out the possibility that a patient harbors another variant that can impact medication efficacy and side effects.
