Mutation c.359_363delGTATTinsATAC in the COL4A5 Causes alport syndrome in a Chinese family
چکیده انگلیسی

The X-linked form of Alport syndrome is associated with mutations in the COL4A5 gene, which is located at Xq22.3 and encodes the α5 chain of type IV collagen. Here we clinically characterized a Chinese family with Alport Syndrome, but no ocular or hearing abnormalities have been observed in any patient in the family. Through Linkage analysis and direct DNA sequencing, a novel complex deletion/insertion mutation c.359_363delGTATTinsATAC in the COL4A5 gene was identified in the family. The mutation was found in all affected family members, but was not present in the unaffected family individuals or the 200 controls. The predicted mutant protein in the family is a truncated protein consisting of only 153 residues. Our report for the first time revealed that the frameshift mutation in the type IV collagen chain α5 causes only renal disease, without extrarenal lesion. Our study broadens genotypic and phenotypic spectrum of COL4A5 mutations associated with Alport syndrome.


► Mutation c.359_363delGTATTinsATAC in the COL4A5 gene was identified in an AS family.
► c.359_363delGTATTinsATAC mutation truncated COL4A5 protein with aberrant 33 residues.
► The frameshift mutation in COL4A5 causes only renal disease, without extrarenal lesion.
► Broadens genotypic and phenotypic spectrum of COL4A5 mutations associated with AS.
