PG4KDS - Priority Genes

SLCO1B1 (solute carrier organic anion transporter family member 1B1) is a drug transporter that helps the body get rid of certain medicines through the liver. There are many medications that may be affected by SLCO1B1 (see this link

There are many variations or genetic differences in the gene for SLCO1B1. These differences in the SLCO1B1 gene can lead to the production of a transport protein that that does not function normally to help the body get rid of drugs. A system designed to classify patients into 3 genotype categories based on the function of SLCO1B1 is used by clinicians to help guide drug therapy decisions.

Priority genotypes

Routine genotypes. We do not routinely adjust medicine doses based on the following genotypes, except in rare instances:
