The invention provides a method for predicting statin responsiveness in a human, the method comprising testing a sample of nucleic acid from said human for the presence or absence of a single nucleotide polymorphism (SNP) in the nucleotide sequence of SEQ ID NO:903 (rs3732788), wherein said human is determined to have an increased statin responsiveness due to the presence of C at position 101 of SEQ ID NO:903 or the presence of G at position 101 of its complement. Further provided are uses of a detection reagent and a kit for predicting said statin responsiveness.
