Inclusion rule
Evidence-backed genomics projects with an explicit connection to one or more GCC states through sample origin, a submitting or data-producing institution, or an explicit regional research scope.
Repository discovery and grouping
NCBI BioProject was searched using exact quoted GCC country names across all fields. Repeated submissions sharing country, submitter, registration date, data type, and narrative were grouped into one series.
Evidence grades
Grade A records have official or primary evidence with durable project, accession, or dataset corroboration. Grade B records have strong evidence with less complete public corroboration than grade A. 5,601 grade-C candidates remain outside this release pending corroboration.
Interpretation cautions
- Atlas is a public research index, not a clinical database.
- Repository registration confirms a durable regional record, not current operating activity.
- Country counts overlap when a record covers multiple GCC states.
- Participant totals must not be summed across related or overlapping cohorts.
Corrections and versioning
Every release is dated and versioned. To suggest a correction or a missing project, email the public accession or source to nuqta@nuqta.sa.
