Genetic determinants of childhood and adult height associated with osteosarcoma risk.

ABSTRACT: BACKGROUND:Although increased height has been associated with osteosarcoma risk in previous epidemiologic studies, to the authors' knowledge the relative contribution of stature during different developmental timepoints remains unclear. Furthermore, the question of how genetic determinants of height impact osteosarcoma etiology remains unexplored. Genetic variants associated with stature in previous genome-wide association studies may be biomarkers of osteosarcoma risk. METHODS:The authors tested the associations between osteosarcoma risk and polygenic scores for adult height (416 variants), childhood height (6 variants), and birth length (5 variants) in 864 osteosarcoma cases and 1879 controls of European ancestry. RESULTS:Each standard deviation increase in the polygenic score for adult height, corresponding to a 1.7-cm increase in stature, was found to be associated with a 1.10-fold increase in the risk of osteosarcoma (95% confidence interval [95% CI], 1.01-1.19; P =.027). Each standard deviation increase in the polygenic score for childhood height, corresponding to a 0.5-cm increase in stature, was associated with a 1.10-fold increase in the risk of osteosarcoma (95% CI, 1.01-1.20; P =.023). The polygenic score for birth length was not found to be associated with osteosarcoma risk (P =.11). When adult and childhood height scores were modeled together, they were found to be independently associated with osteosarcoma risk (P =.037 and P = .043, respectively). An expression quantitative trait locus for cartilage intermediate layer protein 2 (CILP2), rs8103992, was significantly associated with osteosarcoma risk after adjustment for multiple comparisons (odds ratio, 1.35; 95% CI, 1.16-1.56 [P = 7.93×10-5 and Padjusted =.034]). CONCLUSIONS:A genetic propensity for taller adult and childhood height attainments contributed independently to osteosarcoma risk in the current study data. These results suggest that the biological pathways affecting normal bone growth may be involved in osteosarcoma etiology.

Project description:BackgroundNeuroblastoma 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.MethodsWe 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.ResultsAn 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.ConclusionsGenetic 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.

Project description:BackgroundAdult height is associated with risk of several diseases, but the breadth of such associations and whether these associations are primary or due to confounding are unclear. We examined the association of adult height with 50 diseases spanning multiple body systems using both epidemiological and genetic approaches, the latter to identify un-confounded associations and possible underlying mechanisms.MethodsWe examined the associations for adult height (using logistic regression adjusted for potential confounders) and genetically determined height (using a two-sample Mendelian randomisation approach with height-associated genetic variants as instrumental variables) in 417,434 individuals of white ethnic background participating in the UK Biobank. We undertook pathway analysis of height-associated genes to identify biological processes that could link height and specific diseases.ResultsHeight was associated with 32 diseases and genetically determined height associated with 12 diseases. Of these, 11 diseases showed a concordant association in both analyses, with taller height associated with reduced risks of coronary artery disease (odds ratio per standard deviation (SD) increase in height ORepi = 0.80, 95% CI 0.78-0.81; OR per SD increase in genetically determined height ORgen = 0.86, 95% CI 0.82-0.90), hypertension (ORepi = 0.83, 95% CI 0.82-0.84; ORgen = 0.88, 95% CI 0.85-0.91), gastro-oesophageal reflux disease (ORepi = 0.85, 95% CI 0.84-0.86; ORgen = 0.94, 95% CI 0.92-0.97), diaphragmatic hernia (ORepi = 0.81, 95% CI 0.79-0.82; ORgen = 0.91, 95% CI 0.88-0.94), but increased risks of atrial fibrillation (ORepi = 1.42, 95% CI 1.38-1.45; ORgen = 1.33, 95% CI 1.26-1.40), venous thromboembolism (ORepi = 1.18, 95% CI 1.16-1.21; ORgen = 1.15, 95% CI 1.11-1.19), intervertebral disc disorder (ORepi = 1.15, 95% CI 1.13-1.18; ORgen = 1.14, 95% CI 1.09-1.20), hip fracture (ORepi = 1.19, 95% CI 1.12-1.26; ORgen = 1.27, 95% CI 1.17-1.39), vasculitis (ORepi = 1.15, 95% CI 1.11-1.19; ORgen = 1.20, 95% CI 1.14-1.28), cancer overall (ORepi = 1.09, 95% CI 1.08-1.11; ORgen = 1.06, 95% CI 1.04-1.08) and breast cancer (ORepi = 1.08, 95% CI 1.06-1.10; ORgen = 1.07, 95% CI 1.03-1.11). Pathway analysis showed multiple height-associated pathways associating with individual diseases.ConclusionsAdult height is associated with risk of a range of diseases. We confirmed previously reported height associations for coronary artery disease, atrial fibrillation, venous thromboembolism, intervertebral disc disorder, hip fracture and cancer and identified potential novel associations for gastro-oesophageal reflux disease, diaphragmatic hernia and vasculitis. Multiple biological mechanisms affecting height may affect the risks of these diseases.

Project description:Obesity represents a major health burden to both developed and developing countries. Furthermore, the incidence of obesity is increasing in children. Obesity contributes substantially to mortality in the United States by increasing the risk for type 2 diabetes, cardiovascular-related diseases, and other comorbidities. Despite environmental changes over past decades, including increases in high-calorie foods and sedentary lifestyles, there is very clear evidence of a genetic predisposition to obesity risk. Childhood obesity cases can be categorized in one of two ways: syndromic or non-syndromic. Syndromic obesity includes disorders such as Prader-Willi syndrome, Bardet-Biedl syndrome, and Alström syndrome. Non-syndromic cases of obesity can be further separated into rarer instances of monogenic obesity and much more common forms of polygenic obesity. The advent of genome-wide association studies (GWAS) and next-generation sequencing has driven significant advances in our understanding of the genetic contribution to childhood obesity. Many rare and common genetic variants have been shown to contribute to the heritability in obesity, although the molecular mechanisms underlying most of these variants remain unclear. An important caveat of GWAS efforts is that they do not strictly represent gene target discoveries, rather simply the uncovering of robust genetic signals. One clear example of this is with progress in understanding the key obesity signal harbored within an intronic region of the FTO gene. It has been shown that the non-coding region in which the variant actually resides in fact influences the expression of genes distal to FTO instead, specifically IRX3 and IRX5. Such discoveries suggest that associated non-coding variants can be embedded within or next to one gene, but commonly influence the expression of other, more distal effector genes. Advances in genetics and genomics are therefore contributing to a deeper understanding of childhood obesity, allowing for development of clinical tools and therapeutic agents.
