ABSTRACT
Alport syndrome and autosomal dominant polycystic kidney disease are monogenic causes of chronic kidney disease and end-stage kidney failure. We present a case of a man in his 60s with progressive chronic kidney disease, bilateral sensorineural hearing loss and multiple renal cysts. Genetic analysis revealed a heterozygous variant in COL4A3 (linked to Alport syndrome) and in the GANAB gene (associated with a milder form of autosomal dominant polycystic kidney disease). Although each variant confers a mild risk of developing end-stage kidney disease, the patient presented a pronounced and accelerated progression of chronic kidney disease, which goes beyond what would be predicted by adding up their individual effects. This suggests a potential synergic effect of both variants, which warrants further investigation.
