Clinical Phenotyping
Clinical history :

- Extra-renal cysts – hepatic, pancreatic, other
- GI complications – diverticulae, herniae (including type and surgical correction)
- Cardiovascular complications – valvular heart disease, aortic aneurysms
- CNS complications – including presence and size of intra-cranial aneurysms
- Exposures – including caffeine, tobacco, iodinated contrast, hormonal therapies and oral contraception, environmental toxins
- Non-ADPKD co-morbid conditions and medications
