Polycystic kidney disease is defined as a heritable disorder with diffuse involvement of both kidneys without dysplasia other than cysts. The major clinical entities of autosomal recessive polycystic kidney disease and autosomal dominant polycystic kidney disease have a considerable overlap in clinical presentations and radiographic features in the pediatric population. We experienced three cases of autosomal recessive polycystic kidney disease of neonate who expired within 24 hours due to respiratory difficulty and the other case was detected by gross hematuria. So we report four cases with brief review of literatures.

Adult polycystic liver disease (PLD) is a rare, benign condition association with autosomal dominant polycystic kidney disease (ADPKD). It is an autosomal dominantly inherited disorder characterized by multiple diffuse cystic lesions of the liver parenchyma. Significant symptoms or complications from liver involvement can occur cases. Surgical therapy is the mainstay of therapy including laparoscopic or open fenestration with or without hepatic resection and orthotopic liver transplantation. We report the literature addressing the presence of abdominal discomport, a case of a patient with PLD. This case showed the typical ultrasonogaphic and computer tomogaphic findings of this disease.

Polycystic kidney disease (PKD) is a common hereditary disorder which is characterized by fluid-filled cysts in the kidney. Mutation in either PKD1, encoding polycystin-1 (PC1), or PKD2, encoding polycystin-2 (PC2), are causative genes of PKD. Recent studies indicate that renal cilia, known as mechanosensors, detecting flow stimulation through renal tubules, have a critical function in maintaining homeostasis of renal epithelial cells. Because most proteins related to PKD are localized to renal cilia or have a function in ciliogenesis. PC1/PC2 heterodimer is localized to the cilia, playing a role in calcium channels. Also, disruptions of ciliary proteins, except for PC1 and PC2, could be involved in the induction of polycystic kidney disease. Based on these findings, various PKD mice models were produced to understand the roles of primary cilia defects in renal cyst formation. In this review, we will describe the general role of cilia in renal epithelial cells, and the relationship between ciliary defects and PKD. We also discuss mouse models of PKD related to ciliary defects based on recent studies.

Tolvaptan is a highly selective vasopressin receptor 2 antagonist that regulates cyclic adenosine monophosphate levels to inhibit both epithelial cell proliferation and chloride ion excretion, two mechanisms known to induce cyst expansion in autosomal dominant polycystic kidney disease (ADPKD). Tolvaptan is currently the preferred treatment of rapidly progressive disease ADPKD in adult patients; however, since cyst formation in ADPKD begins early in life, (frequently in utero), and significant disease progression with cyst expansion occurs in the first decade, tolvaptan may be advantageous as a preemptive treatment in children with ADPKD. Tolvaptan has already been used to successfully treat refractory edema or hyponatremia in children; this literature review provides insight into the biochemical basis of its action to contextualize its use in the pediatric population.

Polycystic kidney disease (PKD) is a common genetic disorder in which extensive epithelial-lined cysts develop in the kidneys. In previous studies, abnormalities of polycystin protein and its interacting proteins, as well as primary cilia, have been suggested to play critical roles in the development of renal cysts. However, although several therapeutic targets for PKD have been suggested, no early diagnosis or effective treatments are currently available. Current developments are active for treatment of PKD including inhibitors or antagonists of PPAR-${\gamma}$, TNF-${\alpha}$, CDK and VEGF. These drugs are potential therapeutic targets in PKD, and need to be determined about pathological functions in human PKD. It has recently been reported that the alteration of epigenetic regulation, as well as gene mutations, may affect the pathogenesis of PKD. In this review, we will discuss recent approaches to PKD therapy. It provides important information regarding potential targets for PKD.

Since the American College of Medical Genetics and Genomics and Association of Molecular Pathology published their guidelines in 2015, most interpretations of genetic tests have followed them. However, all variants have only limited evidence along 28 interpretation standards, especially de novo variants. When de novo variants, which are classified as variants of uncertain significance (VUS) due to lack of evidence, are detected, segregation in the affected family could provide an important key to clarifying the variants. Autosomal dominant polycystic kidney disease is the most common inherited kidney disorder with pathogenic variants in the PKD1 or PKD2 genes. We detected a novel in-frame deletion variant in the PKD1 gene, c.7575_7577del (p.(Cys2526del)), which was interpreted as a VUS. We analyzed this variant in a Korean family to decide for segregation. Here, we report the variant as a likely pathogenic variant based on the evidence of segregation in three affected relatives and two unaffected members.

Tuberous sclerosis complex (TSC, MIM#191100) is an autosomal dominant neurocutaneous syndrome caused by mutation or deletion of TSC1 encoding hamartin or TSC2 encoding tuberin and characterized by seizure, mental retardation, and multiple hamartomas or benign tumors in the skin, brain, retina, heart, kidney, and lungs. The TSC2 gene on chromosome 16p13.3 lies adjacent to the PKD1 gene which is responsible for autosomal dominant polycystic kidney disease (MIM#173900). The TSC2/PKD1 contiguous gene syndrome (TSC2/PKD1 CGDS, MIM#600273) is caused by deletion of both TSC2 and PKD1 gene. We recently experienced a 15 month-old boy and a 26 month-old girl with TSC2/PKD1 CGDS confirmed by multiplex ligation-dependent probe amplification (MLPA) analysis. They showed not only typical neurologic manifestations of TSC such as epilepsy, subependymal nodules, and subcortical tubers, but also polycystic kidney disease. The contiguous gene syndrome involving PKD1 and TSC2 should be suspected in children with enlarged polycystic kidneys and TSC. MLPA analysis is a useful method for the genetic confirmation of TSC2/PKD1 CGDS.

microRNAs (miRNAs) are small non-coding RNAs that regulate gene expression by targeting the 3'-untranslated region of multiple target genes. Pathogenesis results from defects in several gene sets; therefore, disease progression could be prevented using miRNAs targeting multiple genes. Moreover, recent studies suggest that miRNAs reflect the stage of the specific disease, such as carcinogenesis. Cystic diseases, including polycystic kidney disease, polycystic liver disease, pancreatic cystic disease, and ovarian cystic disease, have common processes of cyst formation in the specific organ. Specifically, epithelial cells initiate abnormal cell proliferation and apoptosis as a result of alterations to key genes. Cysts are caused by fluid accumulation in the lumen. However, the molecular mechanisms underlying cyst formation and progression remain unclear. This review aims to introduce the key miRNAs related to cyst formation, and we suggest that miRNAs could be useful biomarkers and potential therapeutic targets in several cystic diseases.
