Genomic and phenotypic correlates of mosaic loss of chromosome Y in blood.

Mosaic loss of Y (mLOY) is the most common somatic chromosomal alteration detected in human blood. The presence of mLOY is associated with altered blood cell counts and increased risk of Alzheimer disease, solid tumors, and other age-related diseases. We sought to gain a better understanding of genetic drivers and associated phenotypes of mLOY through analyses of whole-genome sequencing (WGS) of a large set of genetically diverse males from the Trans-Omics for Precision Medicine (TOPMed) program.

The expected polygenic risk score (ePRS) framework: an equitable metric for quantifying polygenetic risk via modeling of ancestral makeup.

Polygenic risk scores (PRSs) depend on genetic ancestry due to differences in allele frequencies between ancestral populations. This leads to implementation challenges in diverse populations. We propose a framework to calibrate PRS based on ancestral makeup.

Migratory movements of bats are shaped by barrier effects, sex-biased timing and the adaptive use of winds.

Background: Migratory bats perform seasonal movements between their summer and winter areas. When crossing ecological barriers, like the open sea, they are exposed to an increased mortality risk due to energetically demanding long-distance flights and unexpected inclement weather events. How such barriers affect bat migratory movements is still poorly known.

Adapting an early autism caregiver coaching intervention for telehealth delivery in low-resource settings: A South African study of the 'what' and the 'why'.

We were busy with an early autism caregiver-coaching programme in South Africa, when COVID-19 stopped all in-person work. We changed the programme so it could be done using computers and/or phones. Here, we describe programme changes (which we call the 'what') and the reasons for those changes (which we call the 'why').
