Abstract
Background
Neuroblastoma is the most common pediatric solid tumor. MYCN-amplification is an important negative prognostic indicator and inherited genetic contributions to risk are incompletely understood. Genetic determinants of stature increase risk of several adult and childhood cancers, but have not been studied in neuroblastoma despite elevated neuroblastoma incidence in children with congenital overgrowth syndromes.Methods
We investigated the association between genetic determinants of height and neuroblastoma risk in 1538 neuroblastoma cases, stratified by MYCN-amplification status, and compared to 3390 European-ancestry controls using polygenic scores for birth length (five variants), childhood height (six variants), and adult height (413 variants). We further examined the UK Biobank to evaluate the association of known neuroblastoma risk loci and stature.Results
An increase in the polygenic score for childhood stature, corresponding to a ~0.5 cm increase in pre-pubertal height, was associated with greater risk of MYCN-amplified neuroblastoma (OR = 1.14, P = .047). An increase in the polygenic score for adult stature, corresponding to a ~1.7 cm increase in adult height attainment, was associated with decreased risk of MYCN-amplified neuroblastoma (OR = 0.87, P = .047). These associations persisted in case-case analyses comparing MYCN-amplified to MYCN-unamplified neuroblastoma. No polygenic height scores were associated with MYCN-unamplified neuroblastoma risk. Previously identified genome-wide association study hits for neuroblastoma (N = 10) were significantly enriched for association with both childhood (P = 4.0 × 10-3 ) and adult height (P = 8.9 × 10-3 ) in >250 000 UK Biobank study participants.Conclusions
Genetic propensity to taller childhood height and shorter adult height were associated with MYCN-amplified neuroblastoma risk, suggesting that biological pathways affecting growth trajectories and pubertal timing may contribute to MYCN-amplified neuroblastoma etiology.Type

Jennifer L. Cohen
Jennifer L. Cohen, MD is an Associate Professor of Pediatrics in the Division of Medical Genetics. She attended Yale College and then received her MD from the Icahn School of Medicine at Mount Sinai in NYC. She completed a combined residency program at the Children’s Hospital of Philadelphia in Pediatrics and Medical Genetics, before joining the faculty at Duke in 2019. Her research interests and expertise are in perinatal genetic medicine with a current focus on earlier diagnosis and management of rare genetic diseases. She is the physician lead for Pompe disease newborn screening in North Carolina and is actively involved in gene therapy clinical trials for lysosomal storage diseases. Dr. Cohen leads the Duke site for a clinical trial of prenatal enzyme replacement therapy for lysosomal storage diseases. Her long-time research interests and training have led her to pursue the study of in utero treatment for genetic diseases and to advance implementation of more rapid and comprehensive diagnostic testing in fetuses and critically ill infants.
Qingyi Wei
Qingyi Wei, MD, PhD, Professor in the Department of Medicine, is Associate Director for Cancer Control and Population Sciences, Co-leader of CCPS and Co-leader of Epidemiology and Population Genomics (Focus Area 1). He is a professor of Medicine and an internationally recognized epidemiologist focused on the molecular and genetic epidemiology of head and neck cancers, lung cancer, and melanoma. His research focuses on biomarkers and genetic determinants for the DNA repair deficient phenotype and variations in cell death. He is Editor-in-Chief of the open access journal "Cancer Medicine" and Associate Editor-in-Chief of the International Journal of Molecular Epidemiology and Genetics.

Intersections of the upper respiratory microbiome, environmental exposures, and childhood respiratory infections
Early life exposure to and colonization with microbes has a profound influence on the education of the immune system and susceptibility to viral and bacterial infections later in life. My research is focused on the influence of the upper respiratory microbiome on the development of recurrent respiratory infections, including acute otitis media (AOM), the leading cause of antibiotic prescriptions and healthcare consultations among children. Importantly, some children develop recurrent infections that are thought to be linked to dysbiosis of the nasopharyngeal microbiome. My overarching goals are to identify alterations in the upper respiratory microbiome associated with AOM and to elucidate host factors and exposures that predispose some children to the development of recurrent AOM episodes.
Children's Health & Discovery Initiative:
The prenatal period, infancy, childhood, and adolescence, represent critical time periods of human development that include more developmental milestones than any other period of the lifespan. Conditions during these developmental windows – including biological, social, economic, health, and environmental factors – have a profound impact on lifelong health. The Children’s Health and Discovery Initiative (CHDI) was founded on the hypothesis that interventions early in life will improve population health across the lifespan. To this end, the overarching goal of the CHDI is to create a robust coalition of multidisciplinary investigators and a pipeline of infrastructure, data, and research projects focused on developing innovative approaches to identifying and modulating early life factors that impact lifelong health and well-being.
