Summary
We developed the NHRI reference panel (NHRI-RP-1) for efficient rare variant identification in Taiwanese and Han populations. This panel improves genetic risk prediction and supports genome-wide association studies (GWAS).
Area of Science:
- Genomics
- Population Genetics
- Genetic Epidemiology
Background:
- Development of the National Health Research Institutes (NHRI) reference panel (NHRI-RP-1) to improve rare variant identification.
- Support for genome-wide association studies (GWAS) and imputation studies in the Han population.
Purpose of the Study:
- Optimize sample sizes, minor allele frequency (MAF) thresholds, and imputation quality for an aggregated genome reference panel.
- Evaluate clinical applications and GWAS capabilities of the NHRI-RP-1.
Main Methods:
- Utilized 2,561 whole genome sequences from NHRI datasets.
- Compared various parameter combinations (sample size, MAF, imputation quality) against worldwide references.
- Evaluated performance using F1 score, genotype concordance, and r-squared.
Main Results:
- NHRI-RP-1 (2,500 samples, MAF ≥ 2×10⁻⁴, r² ≥ 0) showed superior performance, especially for rare variants.
- Achieved >95% accuracy for nine pathogenic variants in Taiwan Biobank and high accuracy for DRD1 variant imputation.
Conclusions:
- Reference panel choice impacts GWAS outcomes; NHRI-RP-1 is valuable for genetic medicine.
- Population-specific panels like NHRI-RP-1 facilitate polygenic risk score development for Han population diseases.
