Exploring the presence of the GPR126 single nucleotide polymorphism (rs536714306) in periodontal patients of European ancestry.

Abstract

Objective: G protein-coupled receptor 126 (GPR126) gene has been implicated as a potential susceptibility factor for aggressive periodontitis in Japanese patients. This study aimed to investigate the presence of the GPR126 [c.3086 G > A] (rs536714306) polymorphism in patients with periodontitis in a Greek population and periodontal cases of European ancestry. A total of 82 subjects were recruited: 53 patients periodontally compromised (P) and 29 healthy controls (H). GPR126 genotyping was performed using Sanger sequencing. Additionally, data from the Gene-Lifestyle Interactions in Dental Endpoints (GLIDE) consortium were included in this study.

Results: No variants (rs536714306) in the GPR126 gene were detected in any of the samples. The homozygous for the reference allele GG genotype was observed in 100% of participants across all groups examined. Absence of GPR126 [c.3086 G > A] polymorphism indicates no association with susceptibility to periodontitis in a Greek cohort and periodontally compromised cases of European ancestry. This is the first focused report evaluating the presence of this polymorphism in periodontitis patients in a European population. Further genome-wide studies in larger sample and diverse populations are warranted to fully elucidate the potential role of GPR126 polymorphisms in periodontal disease susceptibility.
