Fig. 1From: Elevated polygenic burden for autism is associated with differential DNA methylation at birthDNA methylation data from neonatal blood spots can be used to accurately predict age and maternal smoking status. a Scatterplot of gestational age predicted from DNA methylation data (using an algorithm generated by Knight et al. [35]) against actual gestational age. Autism cases are in red and controls are in green. b Scatterplot of chronological age predicted from DNA methylation data (using the online Epigenetic Clock software [36]) against actual gestational age. Autism cases are in red and controls are in green. c Boxplot of a smoking score derived from DNA methylation data [23] stratified by maternal smoking status during pregnancyBack to article page
