BACKGROUND: Congenital diaphragmatic hernia (CDH) is characterized by a defective closure figof the diaphragm occurring as an isolated defect in 60% of cases. Lung size, liver herniation and pulmonary circulation are major prognostic indices. Isolated CDH genetics is heterogeneous and poorly understood. Whether genetic lesions are also outcome determinants has never been explored. OBJECTIVES: to identify isolated CDH genetic causes, to fine map the mutational burden and to search for a correlation between the genotype and the disease severity and outcome...

OBJECTIVE: There are concerns regarding the potential harms in receipt of prenatal chromosome microarray (CMA) results, particularly variants of uncertain significance (VUS). We examined the influence that the return of genomic results had on parental well-being and perceptions of children's development. METHODS: Parents (n=138) of 83 children who underwent prenatal chromosomal microarray testing completed questionnaires assessing perception of children's development, parent-child attachment, parental mood, parenting competence, martial satisfaction, satisfaction with the decision to undergo testing, and attitudes about genetics at age 12 and/or 36 months...

We report a multiplex family with a GATA1 gene mutation responsible for a massive fetal cerebral hemorrhage occurring at 36 weeks. Two other stillbirth cousins presented with fetal hydrops and congenital hemochromatosis' phenotype at 37 and 12 weeks of gestation. Molecular screening revealed the presence of a c.613G>A pathogenic allelic variation in exon 4 of GATA1 gene in the three male siblings and their carrier mothers. The diagnosis of a GATA1 gene mutation may be suspected in cases of male fetuses with intracerebral bleeding, particularly if a history of prior fetal loss (es) and mild maternal thrombocytopenia are also present...

OBJECTIVE: Fetal samples obtained by invasive techniques are prone to maternal cell contamination (MCC) which may lead to false genotyping results. Our aim was to determine three molecular genetic tests' sensitivity to MCC. METHOD: By mixing experiments 1, 5, 10, 20, 30 and 40% MCC was simulated and significant MCC levels were determined for Sanger DNA sequencing, multiplex ligation-dependent probe amplification (MLPA) and pyrosequencing, a next generation sequencing (NGS) method...

Congenital diaphragmatic hernia is a rare disease associated with high mortality and morbidity. Antenatal ultrasound screening identifies more than 70% of cases, providing the opportunity for in-utero referral to a tertiary care center for expert assessment and perinatal management. Additional genetic and morphologic assessment may be used to rule out associated anomalies. In isolated cases, the outcome may be predicted prenatally by medical imaging. The combination of lung size and liver herniation is a widely accepted method to stratify fetuses into groups with an increasing degree of pulmonary hypoplasia and corresponding mortality rates...

OBJECTIVE: Human primitive erythroblasts produced during early embryogenesis have been found in maternal circulation at early gestation and are considered good target cells for noninvasive prenatal diagnosis. We aimed to gain a better understanding of the biology of primitive erythroblasts and maximize their potential utility for noninvasive prenatal diagnosis. METHODS: Cells were obtained from first trimester human placental tissues. Biological properties including surface antigen composition, differentiation, proliferation, enucleation, and degeneration were studied as gestation progressed...

OBJECTIVE: As diagnostic methodologies evolve, we sought to determine whether invasive testing rates would decline, whether there would be a shift in indications for invasive testing, and whether the diagnostic yield would increase. METHODS: We conducted a retrospective, observational study from 2006 through 2015. We quantified the number of invasive procedures per year and examined what percentage of these procedures yielded abnormal results. We also examined the indications for testing and determined the trend of these indications during the study period...
