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.
Materials And Methods: SNP genotyping of miR-27a (rs895819), miR-499 (rs3746444), and miR-146a (rs2910164) was performed using polymerase chain reaction (PCR)-restriction fragment length polymorphism and tetra amplification-refractory mutation system PCR in 98 patients with RSA and 105 healthy subjects.
Results: Our results showed that the miR-499 rs3746444 and miR-27a rs895819 polymorphisms were significantly associated with RSA risk, whereas no significant differences were observed between the rs2910164 polymorphism and RSA susceptibility.
Conclusion: We proposed that the miR-499 rs3746444 and miR-27a rs895819 polymorphisms were correlated with RSA in our population, but the miR-146a rs2910164 variant was not associated with the risk of RSA.

Background: This case-control study investigates whether miR-27a rs895819 A>G polymorphism is associated with an increased risk of recurrent pregnancy loss (RPL) in Caucasian Greek women.
Methods: This study included 93 women with at least two unexplained miscarriages before the 24th week of gestation (RPL group) and 107 women with no pregnancy loss history (control group). The miR-27a rs895819 A>G polymorphism was detected using PCR amplification, followed by DraIII-HF restriction enzyme digestion.

Background: Single nucleotide polymorphisms (SNPs) in miRNA genes can influence the expression of miRNAs that modulate the PI3K/AKT/GSK3β pathway and play crucial roles in type 2 diabetes mellitus (T2DM) susceptibility. The purpose of this study was to investigate the association of SNPs in miRNA genes targeting the PI3K/AKT/GSK3β pathway with T2DM.
Methods: This case-control study included 1,416 subjects with T2DM and 1,694 non-diabetics.

Background: Peri-implantitis (PI) is characterised by a chronic inflammatory response that affects both the soft and bone tissues around dental implants. Inflammatory condition, coupled with alterations in bone metabolism, may be modulated by miR-27a-3p.
Aim: This research aims to investigate the relationship between miR-27a-3p rs895819 polymorphism with PI susceptibility, along with its effects and mechanism on inflammatory factors.

Background: miRNAs have enormous potential to be used as diagnostic and prognostic markers as well as therapeutic targets in male infertility and diseases of the reproductive system. This study aimed to investigate the association between the two functional genetic variants in the hsa-miR27a (rs2910164) and hsa-miR-146a gene (rs895819) and male infertility in North Macedonian population, as well as to test their association with the values of major seminal parameters.
Methods: The case group included in this study comprised 158 men initially diagnosed with idiopathic male infertility.
