The authors report on a study that evaluated the association of four long noncoding RNA (lncRNA) (ANRIL, lnc-DC, MALAT1, ZFAS1) gene single-nucleotide polymorphisms (SNPs) with susceptibility to rheumatoid arthritis (RA) patients, as well as their expression levels. The gene discussed is ZFAS1; the disease is rheumatoid arthritis.
