Objective: To assess the association of single nucleotide polymorphisms (SNPs) of microRNA-146a (miR-146a) with clinical features of rheumatoid arthritis (RA).
Methods: In 126 patients with RA and 102 matched healthy controls, SNPs of miR-146a rs2910164 locus were determined with a high-resolution melting method. The association of such polymorphisms with disease activity score in 28 joints (DAS28) and clinical features of RA was assessed.
Results: The distribution of SNPs of miR-146a rs2910164 among RA patients did not differ from that of the control group. No significant association was found between miR-146a rs2910164 polymorphism with DAS28. However, RA patients with a GG genotype had a greater chance to develop extra-articular manifestations (P<0.01).
Conclusion: Polymorphisms of miR-146a rs2910164 locus is not an independent risk factor for RA, though its GG genotype may be associated with extra-articular manifestations of RA.

MicroRNA binding site variants-new potential markers of primary osteoporosis in men and women.
Front Genet
October 2024
Laboratory of Genomic Medicine, Endocrinology Research Centre, Moscow, Russia.
Article Synopsis
- The study explores how specific DNA markers related to microRNAs can provide insights into primary osteoporosis, particularly focusing on epigenetic regulation mechanisms.
- Researchers analyzed genetic variants in a cohort of 1,177 individuals from the Volga-Ural region of Russia, looking for connections between these variants and osteoporosis.
- The findings revealed various genetic markers associated with osteoporotic fractures and low bone mineral density, with notable differences based on ethnicity and sex, leading to the development of predictive models for osteoporosis, particularly effective in women.
Association between IL-6, miRNA-146a, MALAT1 genetic polymorphisms and risk of rheumatoid arthritis.

Article Synopsis
- * Key genotypes and alleles linked to RA susceptibility include GC, IL-6-174 C allele, miR-146a CG, and MALAT1 AA, indicating they may serve as risk factors.
- * Increased expression levels of IL-6, miR-146a, and MALAT1 were found in RA patients, suggesting a potential role in the disease that is not solely dependent on the identified SNPs.
Association between Mir-499, Mir-27a, and Mir-146a polymorphisms and their susceptibility to recurrent spontaneous abortion; analysis.

Objective: Recurrent spontaneous abortion (RSA) is defined as two or more pregnancy losses before 24 gestational weeks, accounting for 1-3% of fertile couples. A vast majority of single-nucleotide polymorphisms (SNPs) in some () genes can change the miRNA-mRNA interaction and are associated with the risk of RSA. This study was designed to better elucidate the association between miR-27a, miR-499, and miR-146a polymorphisms and RSA risk.
