The LncRNA PRNCR1 rs13252298 GG genotype is correlated with reducing susceptibility to recurrent spontaneous miscarriage in a southern Chinese population.

Abstract

Background: LncRNAs play diverse roles and participate in various biological processes within the human body. It has been frequently reported that they are involved in the occurrence and development of recurrent spontaneous miscarriage. PRNCR1, a crucial player in several types of cancers, may also have implications for recurrent spontaneous miscarriage risk. However, the correlation between PRNCR1 rs13252298 A > G polymorphism and this risk remains unclear. In summary, we conducted the following experiments to investigate the association between the PRNCR1 polymorphic site rs13252298 and susceptibility to recurrent spontaneous miscarriage.

Method: Our research included 695 healthy controls and 413 patients with recurrent spontaneous miscarriage from southern China. Genotyping was performed using the TaqMan method.

Result: Our findings revealed that there is a relationship between PRNCR1 rs13252298 A > G polymorphism and lower susceptibility to recurrent spontaneous miscarriage (AG and AA: adjusted OR = 0.794, 95% CI = 0.527-1.196, p = 0.2696; GG and AA: adjusted OR = 0.705, 95% CI = 0.542-0.917, p = 0.0092; dominant model: adjusted OR = 0.722, 95% CI = 0.563-0.926, p = 0.0104; recessive model: adjusted OR = 0.949, 95% CI = 0.644-1.398, p = 0.7912).

Conclusion: The results of our study demonstrate that the PRNCR1 rs13252298 A > G allele may contribute to a decreased risk of recurrent spontaneous miscarriage. The rs13252298 polymorphism could potentially serve as a biomarker for detecting recurrent spontaneous miscarriage risk and aiding prevention efforts.
