Abstract
OBJECTIVES To investigate the diagnostic utility of copy-number variant (CNV) detection by chromosomal microarray analysis (CMA) and genotype-phenotype associations in prenatal congenital anomalies of the kidney and urinary tract (CAKUT). METHODS This is a retrospective multi-center study of CNV analysis in 457 fetuses with ultrasound-detected CAKUT and normal karyotypes. Cohorts from published studies were included for further pooled analyses (N = 2746). A literature review of single-nucleotide variant (SNV) and small insertions and deletions (Indel) analysis by whole-exome sequencing was performed to investigate monogenic causes. RESULTS In our multi-center cohort, 5.3% (24/457) of fetuses had pathogenic CNVs (pCNV); 3.9% (14/359) and 10.2% (10/98) in isolated and non-isolated CAKUT, respectively. Fetuses with isolated hyperechogenic kidneys (HEK) had the highest incidence of having pCNVs. In the literature review, 6.6% (180/2746) of fetuses carried pCNVs; 6.1% and 7.5% in isolated and non-isolated CAKUT, respectively. SNV/Indel analysis provided at least 16.5% (63/381) additional diagnostic yield beyond CNV analysis; 12.8% and 23.8% in isolated and non-isolated CAKUT, respectively. CONCLUSION pCNVs comprise a significant proportion of genetic diagnostic findings in prenatal CAKUT, most commonly detected in fetuses with isolated HEK, MCDK, renal agenesis, and non-isolated CAKUT. Monogenic causes should be considered when karyotyping and CMA are nondiagnostic.

Taiwan J Obstet Gynecol 2022; 61:544-550.

Abstract
OBJECTIVE Chromosome 16p11.2 deletions have been recognized as a genetic disorder with well-described postnatal phenotypes. However, the prenatal manifestations are atypical for lacking of enough evidence. CASE REPORT Four pregnant women underwent amniocentesis for cytogenetic analysis and chromosomal microarray analysis (CMA) because of various indications for prenatal diagnosis: prenatal ultrasound abnormalities (cases 1, 2 and 4) and the childbearing history of cerebral palsy child (case 3). No overlapping phenotypes were observed in cases 1, 2 and 4, which might indicate phenotypic diversities in prenatal phenotypes for 16p11.2 microdeletion. All four fetuses showed normal karyotypic results while CMA identified 0.303-0.916 Mb microdeletions of 16p11.2, encompassing BP2-BP3 and BP4-BP5 regions separately. According to the parental CMA verification, case 1 carried a maternal inherited duplication in the region of Xp22.33 and a de novo deletion in the region of Xp21.1. All parents opted for the termination of pregnancies based upon genetic counselling. CONCLUSION Our findings enriched the intrauterine phenotypic features of 16p11.2 microdeletions, which would be beneficial for genetic counselling in clinic. In addition, preimplantation genetic testing was recognized as a first-tier approach for such carriers if they intended to conceive again.

Chromosomal Microarray Analysis in Pregnancies With Corpus Callosum or Posterior Fossa Anomalies. Neurol Genet 2021; 7:e585. [PMID: 34079909 PMCID: PMC8163489 DOI: 10.1212/nxg.0000000000000585] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Accepted: 02/17/2021] [Indexed: 11/15/2022]
Abstract
OBJECTIVE We investigated the detection rate of clinically significant chromosomal microarray analysis (CMA) results in pregnancies with sonographic diagnosis of fetal corpus callosum anomalies (CCA) or posterior fossa anomalies (PFA). METHODS All CMA tests in pregnancies with CCA or PFA performed between January 2015 and June 2020 were retrospectively evaluated from the Israeli Ministry of Health database. The rate of CMA with clinically significant (pathogenic or likely pathogenic) findings was calculated and compared to a local Israeli cohort of 5,541 pregnancies with normal ultrasound. RESULTS One hundred eighty-two pregnancies were enrolled: 102 cases with CCA and 89 with PFA (9 cases had both). Clinically significant CMA results were found in 7/102 of CCA (6.9%) and in 7/89 of PFA (7.9%) cases. The CMA detection rate in pregnancies with isolated CCA (2/57, 3.5%) or PFA (2/50, 4.0%) was lower than in nonisolated cases, including additional CNS and/or extra-CNS sonographic anomalies (CCA-5/45, 11.1%; PFA-5/39, 12.8%), but this was not statistically significant. However, the rate among pregnancies that had extra-CNS anomalies, with or without additional CNS involvement (CCA-5/24, 20.8%; PFA-5/29, 17.2%), was significantly higher compared to all other cases (p = 0.0075 for CCA; p = 0.035 for PFA). Risk of CMA with clinically significant results for all and nonisolated CCA or PFA pregnancies was higher compared to the background risk reported in the control cohort (p < 0.001), but was not significant for isolated cases. CONCLUSIONS Our findings suggest that CMA testing is beneficial for the genetic workup of pregnancies with CCA or PFA, and is probably most informative when additional extra-CNS anomalies are observed.
