The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across approximately 480,000 CpGs in a total of 407 samples, including 50 normal samples from healthy women, 42 matched normal-adjacent breast cancer pairs (84 samples), 263 unmatched breast cancers, 7 normal samples from BRCA1 carriers and 4 BRCA1 breast cancers. ***WARNING: incomplete metadata supplied for this study***

Provenance — who produced it, who reused it

Linked to 20 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.

Deep data QC

metadata only · no data-level QC for this type

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained

No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.

QC cost 24 s compute

measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
