Dr. Kelleher and her group have been developing telehealth-based interventions to improve the mental wellness of those caring for individuals with neurodevelopmental disorders. Here, they will expand an existing caregiver support program (Well-CAST) to families with PWS and another disorder (Williams Syndrome, WS). They will evaluate different...

This study builds on the previous work of Dr. Godler, who developed a high throughput, economical test to detect chromosome 15 disorders in blood spots from newborns. Dr. Wheeler will transfer the technology to a newborn screening program in North Carolina to assess the feasibility of incorporating detection of chromosome 15 disorder into a...

Currently, there are no objective biomarkers of hunger/satiety for PWS, which can be a barrier in PWS research. This study aims to develop an objective biomarker for altered satiety and hyperphagia in PWS using an eye-tracking method (measuring where a person is looking) to measure attentional bias (AB; increased attention) to food. Previously,...

In PWS, a cluster of small nucleolar RNAs (snoRNAs), the SNORD116 cluster, appears to be of critical importance, but the SNORD116 targets have yet to be identified. Dr. Carmichael and his team have engineered neurons that mimic naturally-occurring PWS deletions and are using them to look for alterations in gene expression and regulation. In year...

PWS is not the result of a single gene mutation but rather is caused by the loss of several contiguous genes, some of which interact with each other. In this project, Drs. Bouret and Muscatelli will study a new mouse model that lacks two PWS genes, Magel2 and Necdin. The goal is to understand how Magel2 and Necdin act together to influence brain...
