Abstract: Objective:To further improve the recognition of Alport syndrome. Methods: The patients with
COL4A3, COL4A4 or COL4A5 mutations, admitted to Department of Pediatric, Peking University First Hospital from 2005 to 2009, were retrospectively studied. Their clinical and ultrastructural characteristics were compared between the male patients with X-linked dominant inheritance Alport syndrome (XLAS) and the patients with autosomal recessive inheritance Alport syndrome (ARAS). Results:There were 54 male patients with XLAS and 14 patients with ARAS. Compared with the male patients with XLAS, episodic gross hematuria was prominent (P<0.001) in patients with ARAS. Family history was also different between the two groups (P=0.016). However, there was no significant difference in the age of identification of symptoms, initial manifestations, levels of proteinuria, extrarenal signs and ultrastructural glomerular basement membrane changes between the two groups. Conclusion:There are some features that distinguish between the patients with XLAS and the patients with ARAS.
