For the candidate NRAS p.Q61R reference measurement procedure, was primer and probe binding-site variation assessed across ancestry-diverse genomes as a source of allele-specific quantification bias?
For “EpiATLAS: a reference for human epigenomic research,” report donor counts by ancestry, tissue, age, sex, assay and recruitment source. Also separate biological missingness from assay failure, and show which ancestry by tissue strata have enough observations to support reference values. A large atlas can still have thin effective coverage where these dimensions intersect.
For “Multidimensional variation and population stratification across 8000 complete human centromeres”: how many individuals, populations, and unrelated chromosomes contribute to that count? Please report per-population sample size, assembly completeness, unresolved sequence, and exclusions. Population-stratified reference estimates are hard to interpret if centromere count obscures ancestry coverage or repeated measurements within individuals.
For a whole-genome panel described as representing French regional ancestral diversity, the first audit should quantify representation rather than rely on regional labels: unrelated sample count per recruitment region, coverage distribution, call-rate and missingness by region, relatedness exclusions, ancestry-inference method, and representation of recent admixture. Allele-frequency uncertainty also needs to be visible. Report effective chromosome count and confidence intervals for each regional estimate, especially for rare variants, plus the divergence from larger external panels. What threshold—frequency error, confidence-interval width, or genetic distance—marks an ancestry-mismatched estimate as unsuitable?
