    Rheumatoid arthritis patients taking methotrexate (MTX) >3 months who carry the ATIC 347GG (116Ser/Ser) genotype showed lower disease activity as assessed by the physician (p = 0.02) and fewer swollen joints (p = 0.06) compared with carriers of combined ATIC CG and CC genotypes; and a pharmacogenetic index of the combined variant alleles for MTX pathway gene variants, TYMS *2, ATIC 347C>G (116Ser), and SLC19A1 (RFC-1) 80A>G (27Arg), was associated with less tender joints (p = 0.012), less swollen joints (p = 0.004), less physician-assessed disease activity (p = 0.0004), and less patient-assessed difficulty with physical tasks (p = 0.001).
  • [Psoriasis]
    [folic acid; methotrexate]
    In 330 patients who completed 3 months methotrexate treatment for psoriasis, no significant genotypic associations were found between clinical outcome (e.g. efficacy, toxicity) and 50 SNPs in pathway genes for methotrexate metabolism (ATIC, FPGS, GGH, MTHFR), including 47 common ( >5% minor allele frequency) haplotype-tagging SNPs (r(2) > 0.8) plus 3 additional SNPs.
  • [Arthritis, Rheumatoid]
    Risk or phenotype-associated allele: ATIC 347CC (116Thr/Thr) > GC (116Thr/Ser) > GG (116Ser/Ser) Phenotype: A composite pharmacogenetic index (additive from zero to five) was calculated using the following values: ATIC 347CC or TSER*3/*3 or SLC19A1 80GG or SLC19A1 80GA genotypes were valued as 0, ATIC 347CG or TSER*2/*3 or SLC19A1 80AA genotypes were valued as 1, and ATIC 347GG or TSER*2/*2 genotypes were valued as 2. The sum originating from each component (ATIC + TSER + SLC19A1) was calculated and constitutes the pharmacogenetic index for the patient. There was a significant association between smaller pharmacolgical index and greater number of tender joints (p = 0.002), swollen joints (p = 0.003), greater physician's global assessment of disease activity (p = 0.032), and higher modified Health Assessment Questionnaire (mHAQ) (p = 0.047). Study size: Study population/ethnicity: Significance metric(s): p < 0.05. Type of association: PD; PK; GN; FA
