CD79A and IgA glomerulonephritis: Berger and Hinglais first described IgA nephropathy (IgAN) in 1968, and since then, it has been named Berger disease.[1,2] IgAN is typically characterized by prominent immunofluorescent mesangial IgA deposits detected by immunofluorescence microscopy.[3] IgAN is one of the world’s most prevalent glomerulonephritis (GN) diseases.[4] It has been reported that IgAN has a variable prevalence of 5 to 40%.
