The chromosome locations and identification numbers (ID) for single-nucleotide polymorphisms are shown for each gene found to have associations with lupus nephritis (LN), myeloperoxidase anti-neutrophil cytoplasmic antibody-associated vasculitis (MPO-AAV), proteinase 3 AAV (PR3-AAV), IgA nephropathy (IgAN), or anti-glomerular basement membrane disease (anti-GBM). The gene discussed is PRTN3; the disease is lupus nephritis.
