Summary:
Purpose: The aim of the study was to evaluate the polymorphic variants of single nucleotide polymorphisms of microRNA-related gene DROSHA in relation to the incidence of primary open-angle glaucoma.
Material and methods: Blood samples were obtained from patients with primary open-angle glaucoma (150 subjects) and age-matched healthy controls (159 subjects). The polymorphic variant frequencies of rs6877842 were determined in DNA isolated from the peripheral blood lymphocytes using real-time PCR TaqMan® SNP Genotyping Assay.
Results: The statistical analysis revealed that the genotype GG of DROSHA rs6877842 occurred more frequently in individuals affected by primary
open-angle glaucoma (P < 0.0001). The G allele of the same gene was present mainly in glaucoma patients (P < 0.0001). The presence of both GG and G variants allele are increasing the risk of primary open-angle glaucoma occurrence.
Conclusion: Our experiment revealed that both GG genotype well as the G allele of rs6877842 DROSHA may affect the risk of primary open-angle glaucoma. The analysis of polymorphic variants of other genes involved in miRNA biogenesis could enable identification of people at high risk for glaucoma.
