Activation of lectin complement pathway is associated with various renal diseases, including IgA vasculitis [37], post-streptococcal acute glomerulonephritis [38] and lupus nephritis [39]; however, association between THSD7A-related MN and lectin complement pathway has not been examined. The gene discussed is THSD7A; the disease is Henoch-Schoenlein purpura.
