Abstract: The present invention describes genomic biomarkers that have been discovered to correlate with varied individual responses (efficacy, adverse effect, and other end points) to therapeutic retinoid X receptor modulator, such as bexarotene, in treating diseases such as, non small cell lung cancer. The newly discovered biomarkers and others in linkage disequilibrium with them can be used in companion diagnostic tests which can help to predict drug responses and apply drugs only to those who will be benefited, or exclude those who might have adverse effects, by the treatment.
