OBJECTIVE: We present prenatal diagnosis of low-level mosaicism for trisomy 13 at amniocentesis associated with a favorable outcome. CASE REPORT: A 35-year-old woman underwent amniocentesis at 18 weeks of gestation because of advanced maternal age. Amniocentesis revealed a karyotype of 47,XY,+13[5]/46,XY[20]. Oligonucleotide array comparative genomic hybridization (aCGH) analysis on uncultured amniocytes revealed arr [GRCh37] (13)×3 [0.10], (X,Y)×1 compatible with trisomy 13 mosaicism...

INTRODUCTION: Ovotesticular disorder of sex development (OT-DSD) is a rare disorder of sexual differentiation characterized by the presence of both testicular and ovarian tissue in an individual and the majority of cases have been reported with 46,XX karyotype. In 46,XX cases, testicular differentiation may occur due to the translocation of SRY to the X chromosome or to an autosome. CASE REPORT: Herein, we present a female newborn with a combination of trisomy 13 and SRY (-) XX OT-DSD...

BACKGROUND: Right ventricular outflow tract (RVOT) stents have been used as palliation in patients with severe tetralogy of Fallot (TOF). Radiofrequency perforation of the RVOT has also been described in patients with pulmonary atresia (PA)/ventricular septal defect (VSD). However, RVOT stenting in conjunction with radiofrequency perforation as a means for establishing reliable pulmonary blood flow in patients with PA/VSD has not previously been reported. OBJECTIVES: Our aim is to report our experience with using perforation of plate-like pulmonary valve atresia combined with stenting of RVOT as an alternative and equally efficacious intervention for infants with PA/VSD, as compared to a surgical pulmonary artery shunt (SPS)...

OBJECTIVE: To examine preference for follow-up test in women screened high or intermediate risk in 1(st) or 2(nd) trimester Down syndrome screening. DESIGN: Prospective cohort study. SETTING: Three public hospitals in Hong Kong, China. SAMPLE: Women with term high risk ≥ 1:250 (HR) or intermediate risk 1:251-1:1200 (IR). METHODS: Women screened high risk were asked to decide among 1) an invasive test plus chromosomal microarray (CMA) to obtain more detailed fetal genetic information, 2) a non-invasive cell free prenatal DNA screening (NIPT) to detect trisomies 13, 18 and 21 to avoid procedure related miscarriage, and 3) decline further testing...

BACKGROUND: Common fetal aneuploidies include Down syndrome (trisomy 21 or T21), Edward syndrome (trisomy 18 or T18), Patau syndrome (trisomy 13 or T13), Turner syndrome (45,X), Klinefelter syndrome (47,XXY), Triple X syndrome (47,XXX) and 47,XYY syndrome (47,XYY). Prenatal screening for fetal aneuploidies is standard care in many countries, but current biochemical and ultrasound tests have high false negative and false positive rates. The discovery of fetal circulating cell-free DNA (ccfDNA) in maternal blood offers the potential for genomics-based non-invasive prenatal testing (gNIPT) as a more accurate screening method...

Families that choose to continue a pregnancy with a prenatal diagnosis of Trisomy 13/18 are a minority that present unique challenges for those in charge of their care. This study investigated the extent to which these patients felt supported by their healthcare providers, and any differences in the perceived level of support experienced by those working with a physician versus those working with a genetic counselor. Two online support groups, SOFT and Hope for Trisomy, distributed an online survey to their members...

BACKGROUND AND OBJECTIVES: Congenital heart disease (CHD) is common in trisomy 13 (T13) and trisomy 18 (T18), but surgical repair has not been offered in most centers. Data on outcomes of congenital heart surgery (CHS) for T13 and T18 are lacking. We sought to determine the impact of CHS on in-hospital mortality in T13 and T18. METHODS: Data from the 2004 to 2015 Pediatric Health Information System database were used to identify inpatients with T13 or T18 and CHD...

REVIEW
Russell S Kirby
Although collectively they are fairly common, birth defects receive limited attention as a group of outcomes either clinically or from a public health perspective. This article provides an overview of the prevalence, trends and selected socio-demographic risk factors for several major birth defects, including neural tube defects, cranio-facial anomalies, congenital heart defects, trisomies 13, 18, and 21, and gastroschisis and omphalocele. Attention should focus on strengthening existing registries, creating birth defects surveillance programs in states that do not have them, and standardizing registry methods so that broadly national data to monitor these trends are available...

Current guidelines indicate that in patients with developmental disabilities or congenital anomalies, chromosomal microarray (CMA) is a first-tier diagnostic test. However, for patients with obvious chromosomal syndromes such as trisomy 13, 18, and 21, G-banded karyotyping is still recommended over CMA for establishing a diagnosis. In the case presented herein, a female neonate was suspected of having trisomy 18 based on pre- and postnatal evaluations. Karyotyping was requested but not performed due to insufficient cell growth; Interphase fluorescence in situ hybridization (i-FISH) found an extra copy of chromosome 18...

OBJECTIVES: The biochemical serum markers free β-human chorionic gonadotropin (hCGβ) and pregnancy associated plasma protein A (PAPP-A), used in screening for trisomy 21 (T21), trisomy 18 (T18), and trisomy 13 (T13) during the first trimester, can be measured on different laboratory instruments e.g. Kryptor (Brahms) and Cobas (Roche). We compared the performance of these two analytical instruments when used for first trimester combined testing. DESIGN AND METHODS: Serum samples from 944 singleton pregnant women attending for first trimester combined testing were routinely assayed for hCGβ and PAPP-A on Kryptor, and re-analyzed on Cobas...

BACKGROUND: Since its debut in 2011, cell-free fetal DNA screening has undergone rapid expansion with respect to both utilization and coverage. However, conclusive data regarding the clinical validity and utility of this screening tool, both for the originally included common autosomal and sex-chromosomal aneuploidies as well as the more recently added chromosomal microdeletion syndromes, have lagged behind. Thus, there is a continued need to educate clinicians and patients about the current benefits and limitations of this screening tool to inform pre- and posttest counseling, pre/perinatal decision making, and medical risk assessment/management...

Cardiac intervention remains controversial in patients with trisomy 13 and 18 and little is known about factors that may affect outcomes. The goal of this study was to evaluate preoperative factors and surgical approach with respect to outcomes in these patients. Patients with congenital heart disease and trisomy 13 or 18 presenting to our institution from 2004 through 2015 were retrospectively reviewed. Patients were grouped into complete intervention, palliated intervention, and non-intervention. Pre-intervention variables, timing and type of intervention, post-intervention outcomes, and survival were recorded and comparisons were made between the groups...
