Brief summary: In this large-scale, multicenter DNA sequencing study, probands (and families; n=13 449) with previously undiagnosed, severe, likely monogenic, complex developmental disorders from 24 centers in the UK and Irland were studied by whole exome sequencing and microarray analysis. Multimodal data analysis yielded a diagnosis in 41%, more likely with TRIO family analysis. Probands with a history of extreme prematurity, in utero exposure to antiepileptics and ...

Brief Summary: These authors performed exhaustive saturation genome editing (SGE) of BAP1 (BRCA1-associated protein 1), the disruption of which is linked to tumorigenesis and altered neurodevelopment. 18,108 unique variants were characterized, of which 6,196 were found to have abnormal functions. These were then used to evaluate phenotypic associations in the UK Biobank. BAP1 variants were also characterized in a large population-ascertained tumor collection,...

Brief Summary: this large patient cohort study identified an overrepresentation of functionally damaging variants in MC3R in individuals with constitutional delay of growth and puberty but not in patients with IHH.Melanocortin 3 receptor (MC3R) is a permissive signal expressed by hypothalamic kisspeptin-neurokinin B-dynorphin (KNDY) neurons. It activates puberty through the leptin-proopiomelanocortin pathway in response to nutritional signaling<...

To read the full abstract: Lancet 2019;393:747–757. .This large prospective cohort study recruited from 34 UK fetal medicine units to evaluate the use of prenatal whole genome sequencing in 610 fetuses with a structural abnormality detected on antenatal ultrasound scanning and no chromosomal abnormality. Overall, a diagnostic genetic mutation ...
