Implementation of trio-based prenatal exome sequencing incorporating splice-site and mitochondrial genome assessment in pregnancies with fetal structural anomalies: prospective cohort study.

Ultrasound Obstet Gynecol 2022 Jun 21. Epub 2022 Jun 21.

Genetics and Prenatal Diagnosis Center, Department of Obstetrics and Gynecology, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.

Objective: To evaluate the utility of trio-based prenatal exome sequencing (pES) incorporating splice-site and mitochondrial genome assessment in the prenatal diagnosis of fetuses with structural anomalies and normal CNV-seq results.

Methods: This prospective study included 90 ongoing pregnancies with ultrasound structural anomalies who underwent trio-based pES after receiving normal CNV-seq results from September 2020 to November 2021. By using pES with a panel encompassing exome coding and splicing regions as well as mitochondrial genome for fetuses and parents, we identified the underlying genetic cause of fetal structural anomalies, fetal incidental findings as well as parental carrier status.

Patient Selection for Renal Denervation in Hypertensive Patients: What Makes a Good Candidate?

Vasc Health Risk Manag 2022 13;18:375-386. Epub 2022 May 13.

Macquarie Medical School, Faculty of Medicine, Health and Human Sciences, Macquarie University, Sydney, New South Wales, Australia.

Renal denervation (RDN) as a therapeutic intervention in patients with hypertension has been intensively studied for over a decade, yet a critical question remains unanswered: what kind of patients are the ideal target population for RDN to achieve its maximum clinical benefit? We herein provide a review of current literature to answer questions related to patient selection to identify populations that will benefit most from RDN, drawing first from human studies but also important clues derived from preclinical animal models. Different aspects that may influence the selection of patients such as the cause of hypertension, the severity of hypertension, concurrent pharmaceutical treatment, renal function, and renal artery anatomy are discussed. Based on current evidence, patients who have severe primary hypertension, regardless of medication or degree of renal dysfunction, who have an accessible accessory renal artery, can achieve a desirable response if a thorough ablation is achieved.

Genetics, pathobiology and therapeutic opportunities of polycystic liver disease.

Nat Rev Gastroenterol Hepatol 2022 May 13. Epub 2022 May 13.

Department of Liver and Gastrointestinal Diseases, Biodonostia Health Research Institute-Donostia University Hospital, University of the Basque Country (UPV/EHU), San Sebastian, Spain.

Polycystic liver diseases (PLDs) are inherited genetic disorders characterized by progressive development of intrahepatic, fluid-filled biliary cysts (more than ten), which constitute the main cause of morbidity and markedly affect the quality of life. Liver cysts arise in patients with autosomal dominant PLD (ADPLD) or in co-occurrence with renal cysts in patients with autosomal dominant or autosomal recessive polycystic kidney disease (ADPKD and ARPKD, respectively). Hepatic cystogenesis is a heterogeneous process, with several risk factors increasing the odds of developing larger cysts. Read More

[Nephronophthisis: a pediatric case report].

Arch Argent Pediatr 2022 06;120(3):e142-e146

Servicio de Nefrología Pediátrica, Hospital de Niños Dr. Ricardo Gutiérrez, Ciudad Autónoma de Buenos Aires, Argentina.

Nephronophthisis is an autosomal recessive cystic kidney disease caused by mutations in genes that encode proteins involved in the primary cilia function, resulting in kidney disease and extrarenal manifestations such as retinal degeneration and liver fibrosis. According to the age of development of end-stage chronic kidney disease, three clinical forms of presentation are described: infantile, juvenile and adolescent. Diagnosis is made by a positive genetic test, or a kidney biopsy demonstrating chronic tubulointerstitial changes with thickening of the tubular basement membranes. Read More

Contributions of afferent and sympathetic renal nerves to cystogenesis and arterial pressure regulation in a preclinical model of autosomal recessive polycystic kidney disease.

Am J Physiol Renal Physiol 2022 06 25;322(6):F680-F691. Epub 2022 Apr 25.

Department of Physiology, University of Arizona Health Sciences Center, Tucson, Arizona.

Polycystic kidney disease (PKD) is the most common inheritable cause of kidney failure, and the underlying mechanisms remain incompletely uncovered. Renal nerves contribute to hypertension and chronic kidney disease-frequent complications of PKD. There is limited evidence that renal nerves may contribute to cardiorenal dysfunction in PKD and no investigations of the role of sympathetic versus afferent nerves in PKD. Read More

Primary URECs: a source to better understand the pathology of renal tubular epithelia in pediatric hereditary cystic kidney diseases.

Orphanet J Rare Dis 2022 03 9;17(1):122. Epub 2022 Mar 9.

Department of Pediatric Kidney, Liver and Metabolic Diseases, Hannover Medical School, Hannover, Germany.

Background: In pediatric hereditary cystic kidney diseases, epithelial cell defects mostly result from rare, autosomal recessively inherited pathogenic variants in genes encoding proteins of the cilia-centrosome complex. Consequences of individual gene variants on epithelial function are often difficult to predict and can furthermore depend on the patient's genetic background. Here, we studied urine-derived renal tubular epithelial cells (URECs) from genetically determined, pediatric cohorts of different hereditary cystic kidney diseases, comprising autosomal recessive polycystic kidney disease, nephronophthisis (NPH) and the Bardet Biedl syndrome (BBS).

Division of Nephrology and Hypertension and Robert M. and Billie Kelley Pirnie Translational PKD Center, Mayo Clinic, Rochester, Minnesota

Background: Upregulation of cAMP-dependent and cAMP-independent PKA signaling is thought to promote cystogenesis in polycystic kidney disease (PKD). PKA-I regulatory subunit RI is increased in kidneys of orthologous mouse models. Kidney-specific knockout of RI upregulates PKA activity, induces cystic disease in wild-type mice, and aggravates it in mice. Read More

Department of Pediatric Nephrology and Organ Transplantation, University Hospitals Leuven, Herestraat 49, 3000, Leuven, Belgium.

Polycystic kidney diseases (PKD) are severe forms of genetic kidney disorders. The two main types of PKD are autosomal recessive and autosomal dominant PKD (ARPKD, ADPKD). While ARPKD typically is a disorder of early childhood, patients with ADPKD often remain pauci-symptomatic until adulthood even though formation of cysts in the kidney already begins in children.

Nephronophthisis-Pathobiology and Molecular Pathogenesis of a Rare Kidney Genetic Disease.

Genes (Basel) 2021 11 5;12(11). Epub 2021 Nov 5.

Macquarie Medical School, Faculty of Medicine, Health and Human Sciences, Macquarie University, Sydney, NSW 2109, Australia.

The exponential rise in our understanding of the aetiology and pathophysiology of genetic cystic kidney diseases can be attributed to the identification of cystogenic genes over the last three decades. The foundation of this was laid by positional cloning strategies which gradually shifted towards next-generation sequencing (NGS) based screenings. This shift has enabled the discovery of novel cystogenic genes at an accelerated pace unlike ever before and, most notably, the past decade has seen the largest increase in identification of the genes which cause nephronophthisis (NPHP).

Recent advances in understanding ion transport mechanisms in polycystic kidney disease.

Clin Sci (Lond) 2021 11;135(21):2521-2540

Department of Physiology, Augusta University, Augusta, GA, U.S.A.

This review focuses on the most recent advances in the understanding of the electrolyte transport-related mechanisms important for the development of severe inherited renal disorders, autosomal dominant (AD) and recessive (AR) forms of polycystic kidney disease (PKD). We provide here a basic overview of the origins and clinical aspects of ARPKD and ADPKD and discuss the implications of electrolyte transport in cystogenesis. Special attention is devoted to intracellular calcium handling by the cystic cells, with a focus on polycystins and fibrocystin, as well as other calcium level regulators, such as transient receptor potential vanilloid type 4 (TRPV4) channels, ciliary machinery, and purinergic receptor remodeling.
