Figures & data
Figure 1 Average DNA methylation level in DRD4, SERT and MAOA amplicons at ages 5 and 10 years. * Significant differences (p < 0.001) in average MAOA DNA methylation level between male and female children. MZ, monozygotic; DZ, dizygotic; MZM, monozygotic male; MZF, monozygotic female; DZM, dizygotic male; DZF, dizygotic female.
Figure 2 Longitudinal analysis of DRD4 DNA methylation in MZ and DZ twins. (A) Individual changes in average DRD4 DNA methylation between ages 5 and 10 years. (B) Inter-individual stability correlations for DRD4 DNA methylation, between ages 5 and 10 years. (C) MZ and DZ twin correlations for average DRD4 DNA methylation at age 5. (D) MZ and DZ twin correlations for average DRD4 DNA methylation at age 10. (E) MZ and DZ twin correlations for intraindividual change in DRD4 DNA methylation from age 5 to age 10 years.
Figure 3 Longitudinal analysis of SERT DNA methylation in MZ and DZ twins. (A) Individual changes in average SERT DNA methylation between ages 5 and 10 years. (B) Inter-individual stability correlations for SERT DNA methylation, between ages 5 and 10 years. (C) MZ and DZ twin correlations for average SERT DNA methylation at age 5. (D) MZ and DZ twin correlations for average SERT DNA methylation at age 10. (E) MZ and DZ twin correlations for intraindividual change in SERT DNA methylation from age 5 to age 10 years.
Figure 4 Longitudinal analysis of MAOA DNA methylation in MZ and DZ twins, stratified by sex. (A) Individual changes in average MAOA DNA methylation between ages 5 and 10 years. (B) Inter-individual stability correlations for MAOA DNA methylation, between ages 5 and 10 years. (C) MZ and DZ twin correlations for average MAOA DNA methylation at age 5. (D) MZ and DZ twin correlations for average MAOA DNA methylation at age 10. (E) MZ and DZ twin correlations for intraindividual change in MAOA DNA methylation from age 5 to age 10 years. MZM, monozygotic male; MZF, monozygotic female; DZM, dizygotic male; DZF, dizygotic female.
