Background: Congenital anomalies of the kidney and urinary tract (CAKUT) are the leading cause of end stage renal disease in children. Diagnosis by genetic testing has proven challenging due to its genetic and phenotypic heterogeneity, as well as incomplete penetrance. We report a case on a 16-months old female with a history of renal cysts and a PAX2 mutation. Case presentation: The patient presented with a prenatal diagnosis of Potter sequence and a postnatal diagnosis of renal cysts. An ultrasound at 20 weeks gestation revealed right renal agenesis and possible left renal dysplasia. Post natal genetic analyses identified a novel mutation in PAX2. Conclusion: Cystic kidney disease is often underdiagnosed due to its variable expressivity and wide range of clinical manifestations; PAX2 genetic screening should be considered for all patients with CAKUT.

Background. Nephronophthisis and medullary cystic kidney disease complex refers to the genetic heterogeneous group of inherited tubulointerstital nephritis. Nephronophthisis comprises at last 3 clinical manifestations, has the autosomal recessive pattern of inheritance, appears early in life and is the most frequent inherited kidney disease that causes terminal renal failure in childhood, while medullary cystic kidney disease has the autosomal dominant pattern of inheritance, is less frequent, and terminal renal failure appears later in life. These two forms have similar clinical and morphological findings but extrarenal manifestations, the median ages of occurrence of terminal renal failure, and siblings presence help us distinguish these diseases. Case report. In this article we illustrated the case of a 20- years old patient with the suspicion of having complex nephornophthisis and medullary cystic kidney disease based upon mild renal failure, seen in routinely taken laboratory findings and bilateral cysts in corticomedullary region of the kidneys verified on abdominal ultrasound examination. Conclusion. This disease should rise suspicion in children or adolescents with progressive renal failure, a typical clinical manifestation, blood and urine samples results, bilateral cysts in the corticomedullary region of the kidneys seen during ultrasound examination of the kidneys and family inheritance.

AbstractAlagille syndrome patients present with loss of function mutations in either JAG1 or NOTCH2. About 40-50% of patients have kidney abnormalities, with multi-cystic, dysplastic kidneys being one of the more frequent kidney defects. Additionally, gain-of-function mutations in NOTCH2 are associated with cystic kidneys in Hajdu-Cheney syndrome patients. Conditional inactivation of Notch1, Notch2, or RBPJ within the nephrogenic lineage impairs nephrogenesis and produces proximal tubule cysts in mice. How perturbations in Notch signaling cause renal tubular cysts remains unclear. Here we have determined that inhibition of Notch signaling in the kidney increases Akap12 expression. Ectopic expression of Akap12 in renal epithelia results in abnormally long primary cilia similar to those observed in Notch-signal-deficiency. Both loss of Notch signaling and elevated Akap12 expression disrupt the ability of renal epithelial cells to form spherical structures with a single lumen when grown embedded in matrix. We conclude that Notch signaling regulates Akap12 expression to ensure normal primary cilia length and renal epithelial morphogenesis, and suggest that diseases associated with defective Notch signaling, such as Alagille syndrome, maybe mechanistically related to ciliopathies.Translational StatementThe current study examines how a reduction in Notch signaling results in abnormal renal tubule formation, as occurs in Alagille Syndrome patients with mutations in JAG1 or NOTCH2. The finding that reduced Notch signaling results in abnormally long cilia is suggestive that some of the clinical manifestations in Alagille Syndrome, such as small cystic kidneys, may originate due to defective cilia function. Linking Notch to primary cilia also opens up the possibility that coinheritance of mutations in ciliopathy genes along with a mutation in JAG1 or NOTCH2 may enhance the severity of the clinical phenotypes such as cystic kidney disease and may explain the variable occurrence and onset of kidney disease among Alagille Syndrome patients.

1 Phthalate esters are known to cause hepatic peroxisome proliferation in rodents and, after prolonged administration, hepatocarcinogenesis. Peroxisome proliferators as a group are hepatocarcinogenic. The mechanism is not known but it does not appear to involve a direct genotoxic element. 2 DEHP and DBP have been shown to cause renal cysts in rodents and they also produce renal peroxisome proliferation. There are no data to causally link the two phenomena. 3 Although renal cysts have been noted in haemodialysis patients and haemodialysis is a route of exposure to DEHP, there are no data to suggest a cause and effect relationship. 4 More studies are needed on the mechanism of renal cystogenesis.

<b><i>Background:</i></b> Kidney disease causes major suffering and premature mortality worldwide. With no cure for kidney failure currently available, and with limited options for treatment, there is an urgent need to develop effective pharmaceutical interventions to slow or prevent kidney disease progression. <b><i>Summary:</i></b> In this review, we consider the feasibility of using human pluripotent stem cell-derived kidney tissues, or organoids, to model genetic kidney disease. Notable successes have been made in modelling genetic tubular diseases (e.g., cystinosis), polycystic kidney disease, and medullary cystic kidney disease. Organoid models have also been used to test novel therapies that ameliorate aberrant cell biology. Some progress has been made in modelling congenital glomerular disease, even though glomeruli within organoids are developmentally immature. Less progress has been made in modelling structural kidney malformations, perhaps because sufficiently mature metanephric mesenchyme-derived nephrons, ureteric bud-derived branching collecting ducts, and a prominent stromal cell population are not generated together within a single protocol. <b><i>Key Messages:</i></b> We predict that the field will advance significantly if organoids can be generated with a full complement of cell lineages and with kidney components displaying key physiological functions, such as glomerular filtration. The future economic upscaling of reproducible organoid generation will facilitate more widespread research applications, including the potential therapeutic application of these stem cell-based technologies.
