Long-term follow-up of an Alport syndrome patient with a novel mutation of COL4A5.

ABSTRACT: BACKGROUND:Alport syndrome (AS) is a genetic disease characterized by progressive glomerulonephritis with a high life-time risk for end-stage renal disease (ESRD), sensorineural hearing loss and ocular abnormalities. So far, a lot of mutations were reported in COL4A3, COL4A4 and COL4A5 genes, which are related to AS. METHODS:Whole-exome sequencing in combination with AS-related genes filtering strategy was applied to investigate a Chinese AS family. We also employed Sanger sequencing to confirm the family co-segregation. In addition, we also summed up a long-term follow-up data from 2003 to 2016. RESULTS:In this study, we have detected a novel insertion mutation (c.348_349insTCCGG/p.G117Sfs×40) of COL4A5, which may lead to a truncated protein in the proband. Sanger sequencing confirmed tha
