Determine whether allelic differences associated with the fourth component of complement, type-1 complement receptor expressed on erythrocytes, and Fc receptor FcgRIII contribute to the pathogenesis of IgA glomerulonephritis (IgA-N).\n\nII. Compare genetic anomalies of these key components in immune complex processing and clearance between juvenile vs adult onset IgA-N vs normal controls.', 'detailedDescription': 'PROTOCOL OUTLINE:\n\nParticipants undergo qualitative genetic analysis of complement-related proteins.
