METHODS FOR PREDICTING METHOTREXATE POLYGLUTAMATE LEVELS USING PHARMACOGENETICS

摘要

The present invention provides methods for determining a level of methotrexate polyglutamates (MTXPGs) in an individual undergoing methotrexate (MTX) therapy and for optimizing dose efficacy of MTX therapy in an individual by genotyping the individual at a polymorphic site in at least one folate pathway gene (e.g., a reduced folate carrier (RFC-1) gene, a gamma glutamyl hydrolase (GGH) gene, etc.). Methods are also provided for determining a level of MTXPGs in an individual undergoing MTX therapy and for optimizing dose efficacy of MTX therapy in an individual by generating a pharmacogenetic index based upon the genotype of the individual at a polymorphic site in an RFC-1 gene and/or a GGH gene.
