The authors present the latest evidence supporting genetic contributions to IgA nephropathy, a common form of primary glomerulonephritis throughout the world. No specific causative gene has yet been detected, but defective glycosylation of IgA1 leading to formation of immune complexes has been consistently implicated. The prevalence of familial forms of the condition varies depending on geography and ethnicity. The clinical patterns of these under-recognized familial forms are reviewed here.
