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 Cohen, MD is an Assistant 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 actively involved in the Pompe disease gene therapy trials at Duke. Her long-time research interests and training have led her to pursue the study of in utero treatment for lysosomal storage diseases and to pursue implementation of more rapid and comprehensive neonatal diagnostic testing in 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.
Area of Expertise: Epidemiology
Kyle Walsh
Dr. Walsh is Associate Professor of Neurosurgery and Pathology, Director of the Division of Neuro-epidemiology, and a Senior Fellow in the Duke Center for the Study of Aging and Human Development. He leads Duke’s Neuro-epidemiology Lab, which integrates bench science with statistical methods to study the neurobiology of glial senescence and gliomagenesis. This research interrogates human genomic and epigenomic profiles to identify both heritable and modifiable factors that contribute to neurologic and physical decline, applying these approaches to studying the shared neurobiology of cognition, glial senescence, and gliomagenesis. The lab has a long history studying telomere maintenance in pre-malignant cells and its role in the development of cancer, most notably glioblastoma.
