Autosomal dominant polycystic kidney disease (ADPKD) is a common and severe renal disease. Mutations of PKD1 and PKD2 genes are responsible for approximately 85% and 15% of ADPKD cases, respectively. In the present study, PKD1 and PKD2 genes were analyzed in a large Chinese family with ADPKD using denaturing high‐performance liquid chromatography and DNA sequencing. A novel mutation, c.3623‐3624insGTGT in exon 15 of the PKD1 gene, was identified in all nine affected family members, but not in any unaffected consanguineous relatives or 100 unrelated controls. These findings suggest that the unique 4 bp insertion, c.3623‐3624insGTGT, in the PKD1 gene might be the pathogenic mutation responsible for the disease in this family.
