Using the North American Rheumatoid Arthritis Consortium (NARAC) candidate gene and genome-wide single-nucleotide polymorphism (SNP) data sets, we applied regression methods and tree-based random forests to identify genetic associations with rheumatoid arthritis (RA) and to predict RA disease status. Several genes were consistently identified as weakly(More)
BACKGROUND New evidence has suggested that people with asthma who are homozygous for arginine at aminoacid 16 of the beta2-adrenergic receptor (ADRB2) might not benefit from longacting beta2-agonist therapy. We, therefore, investigated whether ADRB2 polymorphisms affect response to longacting beta2-agonists in combination with inhaled corticosteroids. (More)
BACKGROUND Evidence suggests that variation in the length of the poly-C repeat in the 3' untranslated region (3'UTR) of the β2-adrenergic receptor gene (ADRB2) may contribute to interindividual variation in β-agonist response. However, methodology in previous studies limited the assessment of the effect of sequence variation in the context of poly-C repeat(More)
