1000 Genomes Project (NYGC 30x) East Asian ABO tag SNPs
========================================================

This directory holds a four-marker extract used by examples/run_1kg_eas.sh,
examples/run_1kg_eas_unphased.sh, and tests. It is not a clinical typing panel.

Source VCF (not in this repository):
  ~/.gwaslab/EAS.ALL.split_norm_af.1kg_30x.hg38.vcf.gz

Panel: 1000 Genomes 30x high-coverage (NYGC), EAS super-population, GRCh38,
split/normalized with allele frequencies (GWASLab asset naming).

Sites (GRCh38, contig chr9):
  rs8176747  133255928  C/G
  rs8176746  133255935  G/T
  rs8176719  133257521  T/TC  (left-aligned c.261 insertion)
  rs505922   133273813  C/T

Samples: 504 (phased GT). examples/run_1kg_eas.sh uses --phase auto.
examples/run_1kg_eas_unphased.sh forces --phase unphased on the same file
(--assume-bo is on by default; pass --no-assume-bo to leave double-hets ambiguous).

Research use only. Genotype-inferred ABO groups must not be used for
transfusion or clinical decision-making.
