Variants in SERPINA1 gene may increase risk of death in AAV

People with ANCA-associated vasculitis (AAV) who carry certain variants in SERPINA1 — a gene that’s been previously linked to the autoimmune disease — may have a six times higher risk of death than those without such variants. That’s according to new data from a single-center study in Brazil, in…

Gene variant linked to greater relapse risk in PR3-associated AAV

A specific variant in both copies of the gene that codes for proteinase 3 (PR3) — one of the most common targets of ANCA-associated vasculitis (AAV)-driving antibodies — is linked to a nearly five times higher risk of severe relapse in people with PR3-associated AAV, a study found. While…
