Objectives

Narrative objectives1

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.

Basic objectives2

Others

Basic objectives -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.

Assessment

Primary outcomes

Identification of molecular subtypes of ASD by clustering based on blood DNA methylation data (at the time of analysis)

Key secondary outcomes

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

Other related information

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.
