The eXtraordinarY Babies Study:
Natural History of Health & Neuro-development in Infants and Young Children with Sex Chromosome Trisomy.

NIH/NICHD 1R01HD091251-01 (PI: Tartaglia, co-I: Ross)  9/06/2017–06/30/2022. The aims are to describe the natural history of young children with sex chromosome trisomy from infancy to 5 years, with a focus on early predictors of neurodevelopmental and cardiometabolic outcomes.

Neural Correlates of the Y Chromosome in Autism:
XYY Syndrome as a Genetic Model

Department of Defense Idea Research Grant Proposal # AR140197 (MPI: T.Roberts, J. Ross, 7/1/15-6/30/18): This study evaluates similarities in autism features of boys with XYY syndrome versus idiopathic autism. 

Neuroimaging in ASD Populations

Increased WM and GM in boys with XYY

R21 MH109158-01A1 (MPI: T. Roberts, J. Ross, 04/01/16-3/31/18) "Structural and Functional Characteristics of XYY - Relationship to ASD." This study evaluates potential neuroimaging biomarkers for autism in populations with autism spectrum disorder.

The IDeA States Pediatric Clinical Trials Network

NIH/NICHD 1UG1HD090915-01 (PI: J.Ross) Delaware Nemours/duPont Hospital for Children Site for the IDeA States Pediatric Clinical Trials Network, 9/21/16-8/31/20. The IDeA States Pediatric Clinical Trials Network functions as one component of the overall Environmental influences on Child Health Outcomes (ECHO) Program.

Center for Pediatric Research
