Membrane‐Spanning Protein Genetic Polymorphisms Related to Methotrexate Therapeutic Outcomes in a Chinese Rheumatoid Arthritis Population
AssociationN=100Shuang Lv et al.(2019)· The Journal of Clinical Pharmacology

This pilot study investigated associations between genetic polymorphisms in transporter genes (SLC19A1, ABCC2, ABCB1, ABCC1, ABCC3, ABCG2) and clinical response to methotrexate (MTX) in 100 Chinese rheumatoid arthritis (RA) patients. Multiple SNPs showed significant associations with MTX response: SLC19A1 rs12659 and rs3788200 major alleles were associated with EULAR good/moderate response (RR=1.42-1.45, p=0.03-0.04); ABCC2 rs3740066 major allele was associated with DAS28-ESR low disease activity (RR=0.67, p=0.02). Haplotype analysis identified significant associations of SLC19A1 and ABCC2 haplotypes with clinical response outcomes.

About ABCC1

The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra-and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This full transporter is a member of the MRP subfamily which is involved in multi-drug resistance. This protein functions as a multispecific organic anion transporter, with oxidized glutatione, cysteinyl leukotrienes, and activated aflatoxin B1 as substrates. This protein also transports glucuronides and sulfate conjugates of steroid hormones and bile salts. Alternatively spliced variants of this gene have been described but their full-length nature is unknown. [provided by RefSeq, Apr 2012]
