Abstract
OBJECTIVE The goal of this study was to review and analyze the medical literature for cases of prenatal and/or postnatally diagnosed bilateral renal agenesis (BRA) and create a comprehensive summary of the genetic etiologies known to be associated with this condition. METHODS A literature search was conducted as a scoping review employing Online Mendeliain Inheritance in Man, PubMed, and Cochrane to identify cases of BRA with known underlying genetic (chromosomal vs. single gene) etiologies and those described in syndromes without any known genetic etiology. The cases were further categorized as isolated versus non-isolated, describing additional findings reported prenatally, postnatally, and postmortem. Inheritance pattern was also documented when appropriate in addition to the reported timing of diagnosis and sex. RESULTS We identified six cytogenetic abnormalities and 21 genes responsible for 20 single gene disorders associated with BRA. Five genes have been reported to associate with BRA without other renal anomalies; sixteen others associate with both BRA as well as unilateral renal agenesis. Six clinically recognized syndromes/associations were identified with an unknown underlying genetic etiology. Genetic etiologies of BRA are often phenotypically expressed as other urogenital anomalies as well as complex multi-system syndromes. CONCLUSION Multiple genetic etiologies of BRA have been described, including cytogenetic abnormalities and monogenic syndromes. The current era of the utilization of exome and genome-wide sequencing is likely to significantly expand our understanding of the underlying genetic architecture of BRA.

Prenat Diagn 2020; 40:528-537. [PMID: 32003482 DOI: 10.1002/pd.5658] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 01/14/2020] [Accepted: 01/18/2020] [Indexed: 12/11/2022]
Abstract
Early pregnancy renal anhydramios (EPRA) comprises congenital renal disease that results in fetal anhydramnios by 22 weeks of gestation. It occurs in over 1 in 2000 pregnancies and affects 1500 families in the US annually. EPRA was historically considered universally fatal due to associated pulmonary hypoplasia and neonatal respiratory failure. There are several etiologies of fetal renal failure that result in EPRA including bilateral renal agenesis, cystic kidney disease, and lower urinary tract obstruction. Appropriate sonographic evaluation is required to arrive at the appropriate urogenital diagnosis and to identify additional anomalies that allude to a specific genetic diagnosis. Genetic evaluation variably includes karyotype, microarray, targeted gene testing, panels, or whole exome sequencing depending on presentation. Patients receiving a fetal diagnosis of EPRA should be offered management options of pregnancy termination or perinatal palliative care, with the option of serial amnioinfusion therapy offered on a research basis. Preliminary data from case reports demonstrate an association between serial amnioinfusion therapy and short-term postnatal survival of EPRA, with excellent respiratory function in the neonatal period. A multicenter trial, the renal anhydramnios fetal therapy (RAFT) trial, is underway. We sought to review the initial diagnosis ultrasound findings, genetic etiologies, and current management options for EPRA.

Abstract
Objective To explore the risk for abnormal chromosomal microarray analysis (CMA) findings in pregnancies with oligohydramnios. Methods Data from all CMA analyses performed due to oligohydramnios between 2013 and 2017 were retrospectively obtained from the Israeli Ministry of Health database. The rate of clinically significant (pathogenic and likely pathogenic) findings was compared to a local cohort of pregnancies with normal ultrasound, yielding a 1.4% rate of abnormal CMA results. In addition, a search was conducted through the PubMed database addressing the issue. Results Fifty CMA analyses were performed due to oligohydramnios. The 2% risk for clinically significant CMA finding in pregnancies with oligohydramnios did not differ from the control population of 5541 pregnancies with normal ultrasound - relative risk (RR) 1.4 [95% confidence interval (CI) 0.2-10.2]. Literature search yielded 394 titles, of which four relevant articles were selected, all using fetal karyotyping. Conclusion There is yet insufficient evidence to support invasive prenatal testing in pregnancies with isolated oligohydramnios.

Abstract
We report on a molecular cytogenetic characterization of 15q26 deletion and 2q37.1 duplication in a fetus presenting with intrauterine growth restriction (IUGR), diaphragmatic hernia, multicystic kidneys, left kidney pyelectasis, and clubfeet. A terminal 15q26 deletion and a terminal 2q duplication of at least 10 and 9 Mb, respectively, derived from a maternal translocation, were found. The 15q26 deletion represents a contiguous gene deletion syndrome mainly characterized by IUGR, congenital diaphragmatic hernia, and less frequently kidney defects. This deletion encompasses the IGF1R and COUPTF2 genes, known to lead to fetal growth retardation syndrome. However, kidney malformations are less well known in such conditions, and to the best of our knowledge, no candidate gene has been proposed to date. Here, we review the literature of the 15q26 deletion syndrome and suggest that hypoplastic and multicystic kidneys, the most commonly observed anomalies in this condition, should be considered in the prenatal diagnosis setting. Based on COUPTF2 protein function, we hypothesize that its haploinsufficiency might be responsible for the renal pathology.
