cfDNA in health

This study investigates baseline methylome and fragmentomic profiles in circulating cell-free DNA (cfDNA) from healthy individuals. Two cohorts were assembled: a diurnal cohort to evaluate temporal variation in cfDNA features, and a cross-sectional cohort to assess inter-individual variability. The project’s goal was to generate a reference dataset for plasma cfDNA to support future studies in biomarker discovery and disease detection.

EGAD50000001721	This dataset contains 432 plasma cfDNA samples from healthy individuals, comprising a diurnal cohort of 16 participants and a cross-sectional cohort of 144 participants. Samples underwent capture-based target enrichment using a custom probe set covering 4,991 genomic regions, followed by targeted enzymatic methyl-sequencing on Illumina instruments in 150 bp paired-end mode. The dataset consists of raw FASTQ files generated from the sequencing runs, accompanied by a metadata file containing individual demographic details and sampling information.	unspecified	432
