Polycystin 1

Mutations in PKD1 result in the most common form of autosomal dominant polycystic kidney disease (ADPKD).


The prevalence of autosomal dominant polycystic kidney disease (ADPKD) is 1:400 to 1:1,000 live births. It is not only one of the most common monogenic hereditary diseases; it is also the third most common single cause of end-stage renal disease. Mutations of the PKD1 gene account for about 85% of ADPKD.

Gene Structure

The PKD1 gene spans about 48kb and consists of 46 exons. The gene is located on chromosome 16 (16p13.3-p13.12). The anterior part of the gene is duplicated several times on chromosome 16. These repetitive structures show 95% sequence homology. These gene fragments are transcribed but not translated, so they are considered pseudogenes.


The most obvious symptom is enlarging renal cysts. Such cysts may also occur in the liver, pancreas, arachnoid membrane, and seminal vesicles. Vascular abnormalities include intracranial aneurysms and dolichoectasias, dilatation of the aortic root, and dissection of the thoracic aorta. Also common are mitral valve prolaps and abdominal wall hernias.
