Once identified, these mutations could help us understand better the mechanism leading to the development of this disease and may explain at least in part the phenotypic variability.","The presentation of ADPKD renal and extrarenal manifestations varies widely, even within families, and has been attributed to numerous genetic factors. One principal explanation came with the discovery that renal cyst lining cells from ADPKD patients undergo secondary somatic mutations, selective loss of the second copy of a respective normal polycystic kidney disease (PKD) gene. These somatic mutations can occur in either polycystic kidney disease 1 (PKD1) or polycystic kidney disease 2 (PKD2). Furthermore, various cysts in the same patient have been reported to harbor different somatic mutations. These findings implicated a cellular recessive mechanism for cyst formation in ADPKD, suggesting the possibility that the observed intra-familial variation in disease phenotype may, at least in part, be explained by variation in mutation type, the timing and number of somatic \"second-hit\" mutations in individual family members affected with the disease. However, there is currently very little known about the cellular genetic mechanism leading to cysts development and very few studies, addressing this issue.",[18],"Autosomal Dominant Polycystic Kidney Disease",[],"OBSERVATIONAL",null,[],{"count":24,"type":25},100,"ESTIMATED",[],[28],{"measure":29,"description":30,"timeFrame":31},"The presence of somatic PKD 1\u002F2 gene mutations in cyst epithelial cells","The presence of mutations will be measured by next generation sequencing (NGS) and other tools for mutation analysis.","10 YEARS",[],"ALL","18 Years","100 Years",{"inclusion":37,"exclusion":43,"raw_text":45},[38,39,40,41,42],"Males or females","18 years of age or older","Confirmed diagnosis of ADPKD","Undergoing a native nephrectomy","Willing and able to provide informed consent",[44],"Unable or unwilling to provide informed consent","Inclusion Criteria:\n\n* Males or females\n* 18 years of age or older\n* Confirmed diagnosis of ADPKD\n* Undergoing a native nephrectomy\n* Willing and able to provide informed consent\n\nExclusion Criteria:\n\n* Unable or unwilling to provide informed consent",[47,48],"ADULT","OLDER_ADULT",[50],{"facility":51,"city":52,"state":52,"zip":53,"country":54,"geoPoint":55},"Weill Cornell Medicine","New York","10021","United States",{"lat":56,"lon":57},40.71427,-74.00597,[],[60],{"name":61,"affiliation":12,"role":62},"Priya Velu, MD, PhD","PRINCIPAL_INVESTIGATOR",[64,68,71,74,78,81,84],{"pmid":65,"type":66,"citation":67},"24641620","BACKGROUND","Tan AY, Blumenfeld J, Michaeel A, Donahue S, Bobb W, Parker T, Levine D, Rennert H.
