Abstract
Purpose

Interleukin-6 (IL-6) is a proinflammatory cytokine with pleiotropic effects which has been related to primary open angle glaucoma (POAG) due to its particular effect of protecting the retinal ganglion cells (RGc) from the apoptosis. Different single nucleotide polymorphisms (SNP) have been associated with POAG. The aim of this study was to determine whether an association between IL-6 rs1800795 (-174 G>C) SNP and a higher risk for POAG is present in western Mexican population.

Methods

One hundred and sixty-five unrelated Mexican mestizo patients with POAG and 108 control subjects were included. Genomic DNA was extracted from leukocytes and purified, followed by genotyping and amplification by polymerase chain reaction (PCR) with Taqman Biosystem probes. Allelic and genotypic diversity was evaluated between cases and control subjects.

Results

There was no statistically significant association between allele and genotype frequencies, neither with dominant nor recessive genetic association models (p > 0.05).

Conclusion

Even though there is a role of IL6 in the pathophysiology of POAG, our results ruled out the association between IL-6 and the rs1800795 SNP showing not to be an index of higher risk for POAG in Mexican population.

Resumen
Objetivo

La interleucina 6 (IL-6) es una citoquina proinflamatoria con efectos pleiotrópicos que se ha relacionado con el glaucoma primario de ángulo abierto (GPAA) debido a su efecto particular de protección de las células ganglionares de la retina (CGR) contra la apoptosis. Se han asociado diferentes polimorfismos de un solo nucleótido (PSN) con el GPAA. El objetivo de este estudio fue determinar si existe una asociación entre el PSN de IL-6 rs1800795 (−174 G>C) y un mayor riesgo de padecer GPAA en la población mexicana occidental.

Métodos

Se incluyeron ciento sesenta y cinco pacientes mestizos mexicanos no emparentados con GPAA y 108 sujetos de control. Se extrajo el ADN genómico de los leucocitos y se purificó, seguido de la genotipificación y la amplificación por reacción en cadena de la polimerasa (PCR) con sondas TaqMan® Biosystem®. Se evaluó la diversidad alélica y genotípica entre los casos y los sujetos de control.

Resultados

No hubo asociación estadísticamente significativa entre las frecuencias alélicas y genotípicas, ni con modelos de asociación genética dominante ni recesiva (p > 0,05).

Conclusiones

Aunque existe un papel de la IL6 en la fisiopatología del GPAA, nuestros resultados descartan la asociación entre la IL-6 y el PSN rs1800795 mostrando no ser un índice de mayor riesgo de GPAA en población mexicana.
