Others
YES
The objective of this study is to identify molecular subtypes of autism spectrum disorder using blood DNA methylation analysis and to characterize their biological features.
Others
This study is an observational analysis using existing anonymized blood DNA methylation data and is not intended to evaluate safety, efficacy, pharmacokinetics, or pharmacodynamics. The objective is to exploratorily identify and characterize molecular subtypes of autism spectrum disorder.
Exploratory
Explanatory
Not applicable
Identification of molecular subtypes of ASD by clustering based on blood DNA methylation data (at the time of analysis)
Identification of differentially methylated probes (DMPs) between subtypes with FDR correction
Functional/pathway analyses based on genes proximal to DMPs (e.g., GO analysis, Ingenuity Pathway Analysis)
Estimation of blood cell-type proportions using a reference-based method (e.g., GLINT) and their association with subtypes
Associations between subtypes and clinical phenotypes (ADI-R, ADOS, IQ, adaptive behavior, perinatal history, comorbidities, etc.)
Development of an AI-based prediction model for subtype classification

This study is an observational study without new participant recruitment or intervention, based on secondary analysis of existing anonymized data obtained from the NIMH Data Archive (Simons Simplex Collection). Blood DNA methylation data are analyzed to identify molecular subtypes of autism spectrum disorder and to explore their associations with clinical and behavioral measures.
