SLCO1B1 variants in a patient of African ancestry presenting with rosuvastatin‐induced rhabdomyolysis: A case report

We report a case of an adult woman of African ancestry who was hospitalized with statin induced- rhabdomyolysis. The patient presented to the emergency room with a 2-week history of worsening muscle pain, nausea, vomiting and low oral intake, 1 month after starting 40 mg daily dose of rosuvastatin. Sequencing of SLCO1B1 coding regions revealed the patient was heterozygous for two SLCO1B1 deleterious variants, c.481+1G>T and c.1463G>C (*9), which are more prevalent in patients of African ancestry. This highlights the importance of pharmacogenetic testing in SLCO1B1, which includes a broader range of genetic variants for patients of African ancestry.
