Abstract
OBJECTIVE We performed a 1-year evaluation of a novel strategy of simultaneously analyzing single nucleotide variants (SNVs), copy number variants (CNVs) and copy-number-neutral Absence-of-Heterozygosity from Whole Exome Sequencing (WES) data for prenatal diagnosis of fetuses with ultrasound (US) anomalies and a non-causative QF-PCR result. METHODS After invasive diagnostics, whole exome parent-offspring trio-sequencing with exome-wide CNV analysis was performed in pregnancies with fetal US anomalies and a non-causative QF-PCR result (WES-CNV). On request, additional SNV-analysis, restricted to (the) requested gene panel(s) only (with the option of whole exome SNV-analysis afterward) was performed simultaneously (WES-CNV/SNV) or as rapid SNV-re-analysis, following a normal CNV analysis. RESULTS In total, 415 prenatal samples were included. Following a non-causative QF-PCR result, WES-CNV analysis was initially requested for 74.3% of the chorionic villus (CV) samples and 45% of the amniotic fluid (AF) samples. In case WES-CNV analysis did not reveal a causative aberration, SNV-re-analysis was requested in 41.7% of the CV samples and 17.5% of the AF samples. All initial analyses could be finished within 2 weeks after sampling. For SNV-re-analysis during pregnancy, turn-around-times (TATs) varied between one and 8 days. CONCLUSION We show a highly efficient all-in-one WES-based strategy, with short TATs, and the option of rapid SNV-re-analysis after a normal CNV result.

Abstract
BACKGROUND KCNMA1 mutations have recently been associated with a wide range of dysmorphological, gastro-intestinal, cardiovascular, and neurological manifestations. METHODS Whole exome sequencing was performed in order to identify the underlying pathogenic mutation in two cases presenting with diverse phenotypical manifestations that did not fit into well-known clinical entities. RESULTS In an 8-year-old boy presenting with severe aortic dilatation, facial dysmorphism, and overgrowth at birth a de novo p.Gly375Arg KCNMA1 mutation was identified which has been reported previously in association with gingival hypertrophy, aortic dilatation, and developmental delay. Additionally, in a 30-week-old fetus with severe growth retardation and duodenal atresia a de novo p.Pro805Leu KCNMA1 mutation was identified. The latter has also been reported before in a boy with severe neurological manifestations, including speech delay, developmental delay, and cerebellar dysfunction. CONCLUSION The current report presents the first antenatal presentation of a pathogenic KCNMA1 mutation and confirms the specific association of the p.Gly375Arg variant with early onset aortic root dilatation, gingival hypertrophy, and neonatal overgrowth.

Abstract
Information about the psychological sequelae of pre-eclampsia (PE) is scarce. Post-traumatic stress disorder (PTSD) may develop after exposure to a stress condition. This study explored whether PE predisposes to PTSD in patients and their partners. Primiparas with a recent history of preterm PE (n=18), preterm birth (PT; n=29), term PE (n=23), or uneventful term birth (C; n=43), and most of their partners completed questionnaires measuring PTSD, depression and related psychological factors. About one-fourth of patients developed PTSD after preterm PE as well as after PT. It occurred in 17% after term PE and in none of the control subjects. A substantial minority of partners was also affected. PTSD symptoms were strongly related to individual psychological characteristics (peritraumatic dissociation, negative interpretations of symptoms, and thought suppression) rather than to objective indicators of condition-severity. The data suggest that PE predisposes to PTSD, primarily but not exclusively resulting from concomitant preterm birth.
