REVIEW
Moyra Smith
Delineation of underlying genomic and genetic factors in a specific disease may be valuable in establishing a definitive diagnosis and may guide patient management and counseling. In addition, genetic information may be useful in identification of at risk family members. Gene mapping and initial genome sequencing data enabled the development of microarrays to analyze genomic variants. The goal of this review is to consider different generations of sequencing techniques and their application to exome sequencing and whole genome sequencing and their clinical applications...

Klinefelter syndrome (KS) is the most common sex chromosomal aneuploidy in males. Major cardiovascular and diaphragmatic anomalies are uncommon in this syndrome. Here we report an infant with KS who had tetralogy of Fallot and congenital diaphragmatic hernia, all of which were identified prenatally and managed successfully after birth. Microarray analysis did not reveal any deletions or duplications other than the additional X-chromosome, to account for the additional abnormalities in this infant. To the authors' knowledge, this is the first such report of major cardiac and diaphragm anomaly occurring together, in an infant with KS...

Exosomes are small membrane vesicles with size of 30-100 nm, which were found in bodily fluids including amniotic fluid and saliva. The biological materials in exosomes, such as proteins and RNA, can be used as novel potential biomarkers for diagnostic assays. The purpose of this study was to assess whether exosomal microRNAs (miRNAs) could be used as biomarkers to prenatally diagnose congenital hydronephrosis and to evaluate fetal kidney function. Transmission electron microscopy (TEM), flow cytometry (FACS), and western-blot were applied to identify exosomes in the amniotic fluid from fetuses with congenital hydronephrosis and healthy controls...

As non-communicable diseases such as type 2 diabetes mellitus have their roots in prenatal development and conditions such as maternal gestational diabetes (GDM), we aimed to test this hypothesis in primary cells derived from the offspring of GDM mothers compared to control subjects. We have assessed primary umbilical cord derived cells such as human umbilical vein endothelial cells (HUVECs) and Wharton's jelly derived mesenchymal stem cells (WJMSCs) from both, the offspring of GDM and non-GDM mothers. We have compared the primary isolates in cell based assays measuring proliferation, mitochondrial oxygen consumption, and the ability to support blood vessel growth...

We experienced a case of advanced maternal age in which a fetus was found to be positive for trisomy 18 at re-examination following indeterminate non-invasive prenatal genetic testing (NIPT), the amniotic fluid chromosomal test revealed a normal karyotype, and confined placental mosaicism (CPM) was observed in an SNP microarray analysis of the placenta. The child was born with no defects or complications. In the present case, the result of the original NIPT at week 15 of pregnancy was indeterminate and the subsequent re-examination result was positive; since the definitive normal diagnosis was not reported until the latter half of week 21, the pregnant patient was subjected to psychological stress for a long period of time...

OBJECTIVES: To investigate fetal cases identified at our institution to determine whether an enlarged cavum septi pellucidi or cavum vergae is associated with other fetal abnormalities and whether its presence warrants more detailed investigation of the fetus. METHODS: In a retrospective study, 15 high- and low-risk patients undergoing prenatal sonography who had an enlarged cavum septi pellucidi or cavum vergae identified were reviewed. Data were collected for the sonographic study indication, gestation age at diagnosis of a prominent cavum, and associated anomalies...

Prenatal diagnostics has been impacted by technological changes in the past decade, which have affected the diagnostic yield. The aim of this study was to evaluate the impact of SNP array and non-invasive prenatal testing (NIPT) on the diagnostic yield and the number of invasive tests in our center. The frequency of pathogenic fetal unbalanced chromosome aberrations was studied in 10,005 cases referred for prenatal testing in 2009-2015. Chromosomal SNP microarray analysis replaced karyotyping in all invasively tested pregnancies and since 2014 a choice between NIPT and diagnostic testing with microarray was offered to women with an increased risk for common aneuploidy...

Approximately 1% of the global population is affected by intellectual disability (ID), and the majority receive no molecular diagnosis. Previous studies have indicated high levels of genetic heterogeneity, with estimates of more than 2500 autosomal ID genes, the majority of which are autosomal recessive (AR). Here, we combined microarray genotyping, homozygosity-by-descent (HBD) mapping, copy number variation (CNV) analysis, and whole exome sequencing (WES) to identify disease genes/mutations in 192 multiplex Pakistani and Iranian consanguineous families with non-syndromic ID...

Background.: In the absence of cytogenetic abnormality, fetuses with congenital anomalies of the kidney and urinary tract (CAKUT) with/without other structural anomalies show a higher likelihood of monogenic causes; however, defining the underlying pathology can be challenging. Here, we investigate the value of whole-exome sequencing (WES) in fetuses with CAKUT but normal findings upon karyotyping and chromosome microarray analysis. Methods.: WES was performed on DNA from the cord blood of 30 fetuses with unexplained CAKUT with/without other structural anomalies...

Delta phalanx is a rare abnormality typically associated with additional features. We describe a patient with a phenotype resembling Catel-Manzke syndrome, but with delta phalanx and abnormal vertebrae and ribs. The patient was the only child of half siblings born with a marked prenatal growth deficiency. At 10 years of age, she had a short stature, long face, long and tubular nose with small alae nasi, high palate, short and broad thorax, and short index fingers with radial deviation. There were hyperpigmentations following Blaschko's lines...
