"Edwards Syndrome"

Alana Cavadino, Joan K Morris
Edwards syndrome (trisomy 18) and Patau syndrome (trisomy 13) both have high natural fetal loss rates. The aim of this study was to provide estimates of these fetal loss rates by single gestational week of age using data from the National Down Syndrome Cytogenetic Register. Data from all pregnancies with Edwards or Patau syndrome that were prenatally detected in England and Wales from 2004 to 2014 was analyzed using Kaplan-Meier survival estimates. Pregnancies were entered into the analysis at the time of gestation at diagnosis, and were considered "under observation" until the gestation at outcome...

Trisomy 18 (or Edwards syndrome) has an incidence of 1 in 6,000 to 8,000 live births, making it the second most common trisomy after trisomy 21. Ophthalmologic anomalies include epicanthal folds, hypertelorism, and hypoplastic supraorbital ridges, whereas corneal opacities, microcornea, congenital glaucoma, cataract, retinal depigmentation, retinal vascular tortuosity, colobomatous microphthalmia, and cyclopia are thought to be less common; iridolenticular adhesions have not been previously reported. Our patient was a female with confirmed trisomy 18 with ophthalmologic examination revealing corneal opacities and iridolenticular adhesions...

The use of suxamethonium in our case was uneventful and despite craniofacial anomalies, airway management was straightforward. This case illustrates that pediatric patients with trisomy 18, presenting with potentially acute life-threatening conditions and requiring emergency major surgery can be managed successfully with a multidisciplinary approach.

Methylation-based non-invasive prenatal testing of fetal aneuploidies is an alternative method that could possibly improve fetal aneuploidy diagnosis, especially for trisomy 13(T13) and trisomy 18(T18). Our aim was to study the methylation landscape in placenta DNA from trisomy 13, 18 and 21 pregnancies in an attempt to find trisomy-specific methylation differences better suited for non-invasive prenatal diagnosis. We have conducted high-resolution methylation specific bead chip microarray analyses assessing more than 450,000 CpGs analyzing placentas from 12 T21 pregnancies, 12 T18 pregnancies and 6 T13 pregnancies...

Constitutional trisomy 18 causes Edwards syndrome, which is characterized by intellectual disability and a particular set of malformations. Although this condition carries high mortality during prenatal and early postnatal life, some of the rare infants who survive the first months develop benign and malignant tumors. To determine the tumor profile associated with Edwards syndrome, we performed a systematic review of the literature. This review reveals a tumor profile differing from those of Down (trisomy 21) and Patau (trisomy 13) syndromes...

We investigated the genetic polymorphisms of three short tandem repeat (STR) loci, D18S53, D18S59, and D18S488, on chromosome 18 in fetuses from a Chinese Tianjin Han population. Sixty-four villus samples and 374 amniotic fluid samples were collected from fetuses. Quantitative fluorescence polymerase chain reaction was performed to amplify the STR loci, followed by scanned electrophoresis and quantitative analysis of the fluorescence signals. Hardy-Weinberg equilibrium (HWE) analysis was performed based on the genotype distributions of the STR loci to obtain the following population genetic data: genotype frequency, heterozygosity of observation (HO), polymorphism information content (PIC), probability of discrimination power (PD), and probability of exclusion (PE)...

We discuss the significance of neutrophils with increased, aberrant nuclear projections mimicking "barbed-wire" in a newborn child with trisomy 18 (T18). Increased, aberrant nuclear projections have been previously reported in trisomy of the D group of chromosomes (chromosomes 13, 14, and 15), and we report similar findings in a patient with T18. The peripheral blood smear showed relative neutrophilia with the majority (37%) of neutrophils showing two or more thin, rod-shaped or spike-shaped, and often pedunculated aberrant nuclear projections...

BACKGROUND: Edwards syndrome (ES) is a severe chromosomal abnormality with a prevalence of about 0.8 in 10,000 infants born alive. The aims of this study were to identify candidate proteins associated with ES pregnancies from amniotic fluid supernatant (AFS) using proteomics, and to explore the role of biological networks in the pathophysiology of ES. METHODS: AFS from six second trimester pregnancies with ES fetuses and six normal cases were included in this study...

Mosaic trisomy 18 (Edwards syndrome) in monozygotic diamniotic liveborn twins is rare. We describe such a case involving preterm male infants. Although both infants had a low percentage of trisomy 18 cells in peripheral blood leucocytes, their varied phenotypic presentation of mosaic trisomy 18 resulted in one twin surviving, with the other twin's demise at 1 month of age. Despite the presence of trisomy 18 in peripheral leucocytes, further analysis of a buccal smear and skin biopsy of the surviving twin did not show evidence of trisomy 18...

The non-invasive prenatal test (NIPT) is an accurate and safe test in which blood from the pregnant woman is used to investigate if the unborn child possibly has trisomy 21 (Down's syndrome), trisomy 18 (Edwards' syndrome) or trisomy 13 (Patau syndrome). Since April 2014 the NIPT has been available in the Netherlands as part of the TRIDENT implementation project for those in whom the first trimester combined test showed an elevated risk (> 1:200) of trisomy, or on medical indication, as an alternative to chorionic villous sampling or amniocentesis...

Global developmental delay (GDD) is defined as a significant delay in two or more developmental domains: gross or fine motor, speech/language, cognitive, social/personal and activities of daily living. Many of these children will go on to be diagnosed with intellectual disability (ID), which is most commonly defined as having an IQ <75 in addition to impairment in adaptive functioning. Cytogenetic studies have been performed in 664 Rwandan pediatric patients presenting GDD/ID and/or multiple congenital abnormalities (MCA)...

Trisomy 18 (Edwards syndrome) is the second most common autosomal trisomy after trisomy 21. Medical issues commonly include cardiac defects, such as ventricular septal defect (VSD) and atrial septal defect (ASD). If untreated, these conditions can contribute to the associated infant mortality. The objective of the study was review parent-reported information on 84 cases with full trisomy 18 focusing on prenatal and postnatal assessment and confirmation of cardiac defects and on subsequent treatment with cardiac surgery and post-surgery outcomes...

We evaluated the system accuracy of noninvasive prenatal diagnosis for abnormal chromosome genetic diseases using cell-free fetal DNA in maternal plasma. Previous studies were searched in the MEDLINE database using the following keywords: "prenatal" and "aneuploidy" and "noninvasive or non-invasive" and "maternal". Identified studies were filtered using a QUADAS instrument. Four studies were identified and analyzed using QUADAS. The studies included 4167 cases of Down syndrome patients determined by noninvasive prenatal diagnosis with a sensitivity of 100% and specificity of 99...

Aneuploidy, an abnormal number of chromosomes, has previously been considered irremediable. Here, we report findings that euploid cells increased among cultured aneuploid cells after exposure to the protein ZSCAN4, encoded by a mammalian-specific gene that is ordinarily expressed in preimplantation embryos and occasionally in stem cells. For footprint-free delivery of ZSCAN4 to cells, we developed ZSCAN4 synthetic mRNAs and Sendai virus vectors that encode human ZSCAN4. Applying the ZSCAN4 biologics to established cultures of mouse embryonic stem cells, most of which had become aneuploid and polyploid, dramatically increased the number of euploid cells within a few days...

Craniofacial malformations are common congenital defects caused by failed midline inductive signals. These midline defects are associated with exposure of the fetus to exogenous teratogens and with inborn genetic errors such as those found in Down, Patau, Edwards' and Smith-Lemli-Opitz syndromes. Yet, there are no studies that analyze contributions of synchronous neurocranial and neural development in these disorders. Here we present the first in-depth analysis of malformations of the basicranium of a holoprosencephalic (HPE) trisomy 18 (T18; Edwards' syndrome) fetus with synophthalmic cyclopia and alobar HPE...
