IllnessRenal disease, familial cystic; differential diagnosis

NGS +

[Sanger]

Renal cysts can be clinically insignificant but can also lead to early end-stage renal failure. The cystic kidney is a disease diagnosed by renal size and cyst location and by extra-renal symptoms. Cystic kidney disease (CKD) may also be associated with extra-renal symptoms in multisystemic diseases, as in tuberous sclerosis and von Hippel-Lindau syndrome. Causal pathogenetically, glomerulocystic and medullary forms of CKD and juvenile nephronophthisis remain to be differentiated. Accordingly, CKDs have quite different causes, hereditary, systemic or rarely acquired and can develop in children and adults. Inherited CKDs are often autosomal dominant (ADPKD) or less commonly autosomal recessive CKDs (ARPKD) each with variable expressivity and penetrance. In more than 90% of familial CDKs, the genetic cause can currently be clarified by molecular genetics. Yet, an inconspicuous genetic finding does not imply exclusion of a suspected clinical diagnosis of CKD.
