Abstract
Background/aim: In current literature, there is a notable lack of studies investigating the role of radiation-sensitive protein 51 (RAD-51) in pterygium diagnosis. Nevertheless, reports indicate elevated expression levels of RAD-51 among recurrent pterygium cases compared to those with primary pterygium. However, the genomic involvement of RAD-51 has yet to be explored in any population. This study aimed to assess the contribution of RAD-51 genotypes to pterygium risk in a representative Taiwanese population.
Materials and methods: RAD-51 rs1801320 genotyping was successfully conducted in a Taiwanese cohort comprising 140 pterygium cases and 280 non-pterygium controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technology.
Results: The distribution of RAD-51 rs1801320 genotypes (GG, CG, and CC) in the pterygium group (70.0%, 25.7%, and 4.3%, respectively) did not significantly differ from that in the non-pterygium group (73.6%, 23.6%, and 2.8% for GG, CG, and CC genotypes, respectively; p for trend=0.6337). Carriers of the variant CG and CC RAD-51 rs1801320 genotypes exhibited 1.15- and 1.58-fold increased pterygium risk, respectively (95%CI=0.72-1.84 and 0.53-4.67, p=0.6552 and p=0.5914, respectively). In the dominant model, there appeared to be a slight association between variant genotypes CG and CC and pterygium risk (OR=1.19, 95%CI=0.76-1.87, p=0.0223). Allelic analysis revealed that the RAD-51 rs1801320 variant C allele was not significantly linked to pterygium risk (17.1% versus 14.6%, OR=1.20, 95%CI=0.82-1.78, p=0.3991).
Conclusion: Variant genotypes at RAD-51 rs1801320 were firstly identified to associate with susceptibility to pterygium among Taiwanese individuals. Nonetheless, these findings warrant validation in larger and more diverse populations.
