-Etiology: The cause of dense deposit disease is genetic and non-genetic factors

-Genes involved: Unknown. 

-Pathogenesis: The sequence of events that lead to dense deposit disease is less clear, abnormality in excessive complement activation and complement regulatory protein factor H gene mutations.

-Morphology: The morphology associated with dense deposit disease shows large glomeruli, with an accentuated lobular appearance.

-Histology: The histology associated with dense deposit disease shows proliferation of mesangial and endothelial cells and infiltrating leukocytes.
