0.100 GeneticVariation BEFREE Our results suggest that the RFC-1 80G>A (rs1051266) SNP exerts a potentially protective effect against the risk of adverse drug reactions in Chinese RA patients treated with MTX. 31099054

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE In multivariate analysis, patients with the solute carrier family 19 member 1 (SLC19A1) 80G>A A/A genotype had a better response than those with the A/G or G/G genotype, and patients with the C allele of γ-glutamyl hydrolase (GGH) 16T>C had a better response than those with the T/T genotype.This study showed that the therapeutic response to MTX in Japanese RA patients was associated with the genetic polymorphisms of SLC19A1 80G>A and GGH 16T>C in actual clinical practice. 30175777

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE In conclusion, the RFC1 G80A polymorphism is associated with responsiveness to MTX therapy, but may not be associated with MTX toxicity in RA patients. 27233001

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE The aim of our study was to characterize the association of clinicopathological variables and the SLC19A1/RFC-1 G80A polymorphism in methotrexate (MTX)-related toxicity in Portuguese patients with rheumatoid arthritis. 24350725

2014

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE In these analyses of available data from observational studies, RFC1 80G>A was found to be associated with MTX efficacy, but not toxicity, in RA patients. 24782176

2014

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE The results of this study suggest that the RFC1 G80A polymorphism may be a useful marker for predicting MTX efficacy in Japanese patients with RA. 22971639

rs775144154
0.100 GeneticVariation BEFREE Frequencies of MTHFR C677T and A1298C were similar to those reported in Japanese RA patients, while frequencies of RFC-1 G80A genotypes differed from those reported in RA patients in the United States. 17965559

2007

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE The present data suggest that evaluation of RFC-1 gene 80G>A polymorphism may be a useful tool to optimize MTX therapy in patients with RA. 17325736

2007

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE We investigated the contribution of common genetic polymorphisms in RFC-1 (G80A), ATIC (C347G), and TS (28-bp tandem repeats located in the TS enhancer region [TSER*2/*3]) and of MTXPGs to the effect of MTX in patients with rheumatoid arthritis. 15457444

dbSNP: rs775144154
rs775144154
0.100 GeneticVariation BEFREE We investigated whether polymorphisms in reduced folate carrier (SLC19A1 G80A) and gamma-glutamyl-hydrolase (GGH-401C/T) are predictive of methotrexate polyglutamate (MTXPG) levels in patients with rheumatoid arthritis treated with weekly low-dose methotrexate (MTX). 15564880
