|Annotation=Risk or phenotype-associated allele: rs2267076 T allele Phenotype: Carriers of 1 or 2 copies of the T allele for rs2267076 showed increased risk of any (OR = 2.1, CI 1.05-4.27, p = 0.02) or gastrointestinal-specific (OR = 1.77, CI = 0.65-5.77, p = 0.22) adverse events. Study size: 309 RA patients, including 147 good MTX responders, 101 MTX inefficacy failures, and 61 adverse event (AE) MTX failures (e.g. gastrointestinal (n = 24), abnormal liver function tests (n = 20), haematological (n = 7), skin rashes (n = 6), and other (n = 17). Study population/ethnicity: Rheumatoid arthritis (RA) patients aged over 18 yrs, of White Caucasian ethnic origin, classified as having RA according to ARA criteria that were retrospectively recruited from University Hospital of North Staffordshire (UHNS) and Central Manchester and Manchester Children&apos;s University Hospitals Trust (CMMC) in England. Significance metric(s): OR = 2.1 and 1.77, p = 0.02-0.22. Type of association: GN; PD; TOX; ADR.
