Association of ATG4A single nucleotide polymorphism rs807185 on risk of microscopic polyangiitis in Chinese
1Department of Nephrology, The Second Affiliated Hospital of Guangxi Medical University, Nanning, 530021, China.
Background:
Microscopic polyangiitis is a type of antineutrophil cytoplasmic antibody-associated vasculitis, characterized by a systemic, pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation. Many studies have linked autophagy-related gene polymorphisms to the development of immune diseases. However, the association between autophagy-related genes and microscopic polyangiitis remains unclear.
Objective:
We investigated the association between microscopic polyangiitis and the single nucleotide polymorphism rs807185 in autophagy-associated gene 4A (ATG4A) in the Chinese population.
Methods:
ATG4A single nucleotide polymorphism rs807185 frequency was identified using multiplex polymerase chain reaction and high-throughput sequencing in a cohort with microscopic polyangiitis (n = 181) and a healthy control group (n = 209).
Results:
We found that the control cohort had a higher prevalence of allele A of rs807185 compared to the microscopic polyangiitis cohort. The rs807185A allele was therefore linked to a lower risk of microscopic polyangiitis.
Conclusion:
The single nucleotide polymorphism rs807185 allele A in ATG4A may have a protective effect against microscopic polyangiitis in the Chinese population, but the molecular mechanisms remain unclear.
Insights
The autophagy-associated gene 4A (ATG4A) single nucleotide polymorphism rs807185 allele A may protect against microscopic polyangiitis in the Chinese population. Further research is needed to understand the underlying molecular mechanisms of this association.
Area of Science:
- Genetics
- Immunology
- Molecular Biology
Background:
- Microscopic polyangiitis is an autoimmune disease characterized by inflammation of small blood vessels.
- Autophagy-related genes are implicated in immune system function, but their role in microscopic polyangiitis is not well understood.
Purpose of the Study:
- To investigate the association between a specific single nucleotide polymorphism (SNP) in the autophagy-associated gene 4A (ATG4A), rs807185, and microscopic polyangiitis (MPA) in the Chinese population.
Main Methods:
- A case-control study was conducted with 181 MPA patients and 209 healthy controls from the Chinese population.
- Genotyping for the ATG4A rs807185 SNP was performed using multiplex polymerase chain reaction and high-throughput sequencing.
Main Results:
- The frequency of the A allele of rs807185 was significantly higher in the healthy control group compared to the MPA cohort.
- The presence of the rs807185 A allele was associated with a reduced risk of developing microscopic polyangiitis.
Conclusions:
- The rs807185 A allele in the ATG4A gene may confer a protective effect against microscopic polyangiitis in the Chinese population.
- The precise molecular mechanisms underlying this protective association require further investigation.
