Objective: Autosomal dominant polycystic kidney disease (ADPKD), one of the most common causes of end-stage renal disease, is a monogenic, multisystemic disease characterized by renal cysts and various extrarenal findings. ADPKD is caused by mutations in the polycystic kidney disease 1 (PKD1) (16p13.3) and PKD2 (4q22.1) genes. The genetic analysis of the PKD1 gene is complex because of its large size, the presence of 6 pseudogenes, and allelic heterogeneity. In this study, we aimed to identify the mutations of the PKD1 gene in patients with ADPKD in Sivas, Turkey.Materials and Methods: A total of 27 patients who were diagnosed with ADPKD were included in this study. Their mean age and body mass indices were determined. The gene variants were analyzed by targeted next-generation sequencing method.Results: In 17 (64.3%) of the 27 patients, the variants were detected in PKD1 and/or PKD2 genes. There were 13 patients (48.1%) with PKD1 gene variants and 5 (18.5%) with PKD2 gene variants. Of the 17 patients, 1 had both PKD1 and PKD2 gene variants. We observed that 16 patients with ADPKD (66.6%) had hypertension, and liver cysts were detected in 9 (33.3%) patients.Conclusion: PKD1 gene mutations were found in a significant number of patients with ADPKD, and hypertension is a fre-quently observed finding in them. In some patients, liver cysts may accompany the clinical picture of ADPKD. Our findings provide important insights for the genetic counseling of these patients.
