Identification of novel PKD1 and PKD2 mutations in a Chinese population with autosomal dominant polycystic kidney disease.

ABSTRACT: Autosomal dominant polycystic kidney disease (ADPKD) is one of the most frequently inherited renal diseases caused by mutations in PKD1 and PKD2. We performed mutational analyses of PKD genes in 49 unrelated patients using direct PCR-sequencing and multiplex ligation-dependent probe amplification (MLPA) for PKD1 and PKD2. RT-PCR analysis was also performed in a family with a novel PKD2 splicing mutation. Disease-causing mutations were identified in 44 (89.8%) of the patients: 42 (95.5%) of the patients showed mutations in PKD1, and 2 (4.5%) showed mutations in PKD2. Ten nonsense, 17 frameshift, 4 splicing and one in-frame mutation were found in 32 of the patients. Large rearrangements were found in 3 patients, and missense mutations were found in 9 patients. Approximately 61.4% (27/44) of
