ANCA-associated vasculitides cause inflammation of small blood vessels. Alpha-1 antitrypsin deficiency (SERPINA1) increases risk of certain forms.
How Genetic Is ANCA-Associated Vasculitis?
Genetics plays a meaningful role in ANCA-Associated Vasculitis, with heritability estimated at around 30%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with ANCA-Associated Vasculitis: HLA-DPB1,SERPINA1,PTPN22. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
