Wave alternate title	Wave 1 Technical Pilot ACTION Biomarker Study YC_ACTION
Short description of the wave	The first wave of the technical pilot of the ACTION project (Aggression in Children: Unraveling gene-environment interplay to inform Treatment and interventION strategies Consortium; http://www.action-euproject.eu). The aim of the technical pilot was to test the collection protocols for urine and buccal sample collection in 10-13 year old twins (mean age = 11.6 years, SD = 0.9 years) born between 2002 and 2005. The technical pilot comprised of twin participants with a low aggression score (T-score<65) on the mother-reported ASEBA CBCL Aggression Syndrome Scale at age 3 and/or age 7. Urine samples with minimal information regarding urine collection were collected at two timepoints with an interval of approximately two weeks. Urine samples contributed to the optimization of the biomarker assays and the liquid and gas chromatography mass spectrometry protocols for analyzing urine samples in children. In the technical pilot a urine dipstick and assessment of urine density (specific gravity) were obtained in addition to 15 biomarker assays (creatinine, neopterin, C-peptide, Substance P, Oxidized DNA/RNA, Procalcitonin, total antioxidant capacity, glucose, Thiobarbituric acid reactive species, beta-endorphin, cholecytokin, leu-enkaphalin, dynorphin A, albumin, and neurotensin) , and two metabolomics platforms (liquid chromatography mass spectrometry platform targeting amines and gas chromatography mass spectrometry platform targeting organic acids). Buccal-cell samples were also collected at both time points where samples obtained from wave 1 were genotyped on the Affymetrix Axiom genotyping array.

Wave alternate title	Biochemical Study ACTION Biomarker Study YC_ACTION
Short description of the wave	The biochemical study of the ACTION project (Aggression in Children: Unraveling gene-environment interplay to inform Treatment and interventION strategies Consortium; http://www.action-euproject.eu). The aim of the biochemical study was to further validate the biomarker assays and metabolomics platforms selected during the two waves of the technical pilot (YC_ACTION BB1_1 BB1_2) in a larger sample of 6-11 year old twins born between 2004 and 2009 (mean age = 9.9 years, SD = 1.6 years). The twins were selected based on their mother-rated aggression scores (Achenbach System of Empirically Based Assessment (ASEBA) Child Behavior Checklist) at age 3 and/or 7. The Biochemical study comprised concordant low-scoring twin pairs, concordant high-scoring twin pairs, and a discordant low-high scoring twin pairs. High aggression was defined as having an ASEBA CBCL Aggression Syndrome Scale T-score equal to or larger than 65, and low aggression as an ASEBA CBCL Aggression Syndrome Scale T-score of less than 65. Here, data collection comprised of first-morning urine samples and buccal-cell DNA samples in the twins and family members living at the same address as the participating twin pairs were also asked to provide a buccal-cell DNA sample. During the urine and buccal-cell collection, parents of the twins were asked to complete the ASEBA CBCL for school-aged children (6-18 years) to reflect the current child behaviors, and to provide information about health condition of the twins and conditions of urine collection. Biochemical measurement in urine included a dipstick, density (specific gravity), creatinine, neopterin, C-peptide, Substance P, oxidized DNA/RNA, procalcitonin, total antioxidant capacity, and glucose, and two metabolomics platforms: 1) a liquid chromatography mass spectrometry (LC-MS) platform targeting amines; and 2) a LC-MS platform targeting steroid hormones. Buccal-cell samples were genotyped on the Affymetrix Axiom genotyping array.

Wave alternate title	Main Study ACTION Biomarker Study YC_ACTION
Short description of the wave	The Main Study of the ACTION project (Aggression in Children: Unraveling gene-environment interplay to inform Treatment and interventION strategies Consortium; http://www.action-euproject.eu), after the technical pilots (YC_ACTION BB1_1 and BB1_2) and the Biochemical study (YC_ACTION BB2). Here, data collection of first-morning urine samples for metabolomics biomarker discovery and buccal-cell DNA samples for (epi)genetics was conducted in a large cohort of 6-13 year old twins born between 2004 and 2011 (mean age = 9.5 years, SD = 1.9 years). Family members living at the same address as the participating twin pairs were also asked to provide a buccal-cell DNA sample. The twins were selected to be part of a concordant low-scoring twin pair, a concordant high-scoring twin pair, or a discordant twin pair. Aggression had been assessed in the past by the age-appropriate version of the CBCL (Achenbach System of Empirically Based Assessment (ASEBA) Child Behavior Checklist). During the urine and buccal-cell collection, parents of the twins were asked to complete the ASEBA CBCL for school-aged children (6-18 years) to reflect the current child behaviors, and to provide information about health condition of the twins and conditions of urine collection. Biochemical measurement in urine included a dipstick, density (specific gravity), creatinine, neopterin, C-peptide, Substance P, and oxidized DNA/RNA. Metabolomics data of the Main Study together with the samples obtained in the Biochemical Study (ACTIONBB2) were were obtained from three metabolomics platforms: 1) a liquid chromatography mass spectrometry (LC-MS) platform targeting amines; 2) a LC-MS platform targeting steroid hormones; and 3) a gas chromatography (GC) MS platform targeting organic acids. Buccal-cell samples of the twins from the Main Study together with the samples obtained in the Biochemical Study (ACTIONBB2) were used for genome-wide methylation measurement on the Infinium MethylationEPIC BeadChip Kit (after conclussion of the ACTION project additional twin pairs and siblings were also measured on this platform). DNA samples from all family members were genotyped on the Affymetrix Axiom or Illumina GSA genotyping arrays.

The NTR was established in 1987 and has enrolled around 120.000 twins and a roughly equal number of their relatives. The majority of twin families have participated one or more times in survey studies on a host of epidemiological variables including social demography, personality, lifestyle, somatic and mental health, and subsamples took part in biomaterial collection (e.g. DNA) and dedicated projects for e.g. neuropsychological, biomarker, and behavioral traits. The recruitment into the NTR is fully inclusive without any restrictions on enrolment. The NTR is committed to actively seek the commitment of its participants to science and their continued involvement in NTR research by maintaining a website, electronic newsletters, and the MijnNTR portal that provides personalized feedback to participants. The NTR resources, e.g. the longitudinal phenotyping, the extended pedigree structures, and the multi-generation genotyping allow for future twin-family research that will contribute to gene discovery, causality modelling, and studies of genetic and cultural inheritance of behavioral traits and mental and physical health. In the CD2 portal, only the NTR projects for children and adolescents (<18 years of age) have been included.

The aim of the technical pilot was to test the collection protocols for urine and buccal sample collection in 10-13 year old twins (mean age = 11.6 years, SD = 0.9 years) born between 2002 and 2005. The technical pilot comprised of twin participants with a low aggression score (T-score<65) on the mother-reported ASEBA CBCL Aggression Syndrome Scale at age 3 and/or age 7. Urine samples with minimal information regarding urine collection were collected at two timepoints with an interval of approximately two weeks. Urine samples contributed to the optimization of the biomarker assays and the liquid and gas chromatography mass spectrometry protocols for analyzing urine samples in children. In the technical pilot a urine dipstick and assessment of urine density (specific gravity) were obtained in addition to 15 biomarker assays (creatinine, neopterin, C-peptide, Substance P, Oxidized DNA/RNA, Procalcitonin, total antioxidant capacity, glucose, Thiobarbituric acid reactive species, beta-endorphin, cholecytokin, leu-enkaphalin, dynorphin A, albumin, and neurotensin) , and two metabolomics platforms (liquid chromatography mass spectrometry platform targeting amines and gas chromatography mass spectrometry platform targeting organic acids).

The aim of the technical pilot was to test the collection protocols for urine and buccal sample collection in 10-13 year old twins born between 2002 and 2005 (mean age = 11.6 years, SD = 0.9 years). The technical pilot comprised twin participants with a low aggression score (T-score<65) on the mother-reported ASEBA CBCL Aggression Syndrome Scale at age 3 and/or age 7. Urine samples with minimal information regarding urine collection were collected at two timepoints with an interval of approximately two weeks. Urine samples contributed to the optimization of the biomarker assays and the liquid and gas chromatography mass spectrometry protocols for analyzing urine samples in children. In the technical pilot a urine dipstick and assessment of urine density (specific gravity) were obtained in addition to 15 biomarker assays (creatinine, neopterin, C-peptide, Substance P, Oxidized DNA/RNA, Procalcitonin, total antioxidant capacity, glucose, Thiobarbituric acid reactive species, beta-endorphin, cholecytokin, leu-enkaphalin, dynorphin A, albumin, and neurotensin), and two metabolomics platforms (liquid chromatography mass spectrometry platform targeting amines and gas chromatography mass spectrometry platform targeting organic acids).
