Background:

DNA methylation signatures typically rely on complex, multi-site analyses.
Predicting cell types using DNA methylation often requires extensive datasets.
Existing methods can be computationally intensive and time-consuming.

Purpose of the Study:

To introduce CimpleG, a novel computational framework.
To enable the detection of small CpG methylation signatures.
To facilitate accurate cell-type classification and deconvolution using minimal data.

Main Methods:

Development of the CimpleG computational framework.
Application of CimpleG for identifying single CpG methylation sites.
Validation of CimpleG against established methods for cell-type classification.

Main Results:

CimpleG efficiently detects small DNA methylation signatures.
The framework achieves high accuracy in cell-type classification for blood and somatic cells.
Predictions are based on a single DNA methylation site per cell type, significantly reducing complexity.

Conclusions:

CimpleG offers a time-efficient and effective approach for DNA methylation signature analysis.
The framework simplifies cell-type classification and deconvolution.
CimpleG provides a robust tool for delineating DNA methylation signatures.
