Research Article: Cytotoxic T lymphocyte-associated protein 4 gene polymorphisms are associated with ANCA-associated vasculitis in the Guangxi population of China

Date Published: 2025-09-09

Abstract:
Heredity and epigenetic factors contribute to the pathogenesis of neutrophil-cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Cytotoxic T lymphocyte-associated protein 4 (CTLA-4), an inhibitory receptor regulating T-cell homeostasis and maintaining self-tolerance, has emerged as a key target for immune screening and therapeutics in autoimmunity and cancer. CTLA-4 is associated with various autoimmune diseases; however, the relationship between CTLA-4 polymorphisms and AAV in the Guangxi population of China remains underexplored. In the present case–control study, we evaluated the effects of CTLA-4 polymorphisms on AAV susceptibility in the Guangxi population of China. A total of 343 patients with AAV and 343 healthy controls were recruited. High-throughput sequencing was used to genotype CTLA4 variants, and logistic regression analysis was used to assess their association with AAV risk. The relationship between the haplotypes of CTLA4 single-nucleotide polymorphisms (SNPs) and AAV risk was assessed using the SHEsis platform. Three CTLA4 SNPs— rs62182595, rs16840252 , and rs5742909 — showed significant association with AAV susceptibility. The ATT and GCC haplotypes, comprising these loci, were also associated with an increased risk of AAV. These findings suggest that CTLA4 polymorphisms ( rs62182595, rs16840252 , and rs5742909 ) may contribute to AAV susceptibility in the Guangxi population and offer preliminary markers for risk assessment, early diagnosis, and personalized management of AAV.
