From: Elevated polygenic burden for autism is associated with differential DNA methylation at birth

DNA 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 pregnancy
