- Reads with MAPQ<20 were excluded at variant calling with GATK 3.7 HaplotypeCaller
- QC and filtering
- Data with bad base quality and high %GC content were removed.
Alignment:
Data matched for the following conditions were removed.
- Low mapping rate
- Different insert size
- Gender information mismatch between meta-data and genotype data
- Suspected sex chromosome aberration
Genotyping:
GATK's best practices include a variant filtering step following Variant Quality Score Recalibration (VQSR)
- DP/GP (DP < 5, GQ < 20, DP > 60, GQ < 95)
- Heterozygosity (F>=0.05)
- Hardy-Weinberg equilibrium (p < 10^-6)
- Repeat & Low Complexity
Principal Component Analysis (PCA):
PCA was performed with individuals included in the 1000 genomes project and outliers from Japanese cluster were removed.
After these filtering steps, variants located in the regions listed as the HighConfidenceRegion (Genome-In-A-Bottle project) were flagged. - Analysis method

- We set exclusion criteria for genotypes as follows:
(1) DP < 5, (2) GQ < 20, or (3) DP > 60 and GQ < 95, and regarded these genotypes as missing.
Variants with call rates < 90% were excluded before variant quality score recalibration (VQSR).
After VQSR, we excluded variants located in low-complexity regions (LCR), as defined by mdust software were excluded.
Finally, we used BEAGLE to impute missing genotypes. - Analysis method

- Germline whole genome sequencing data were processed, and the aggregate VCF was calculated. Variants were then filtered based on the following conditions:
(1) Variants that did not pass the VQSR filter were excluded
(2) Multi-allelic sites were excluded
(3) Variants with a call rate below 95% were excluded
(4) Variants deviating from Hardy-Weinberg equilibrium (P < 1e-10) were excluded
(5) Variants with a minor allele count (MAC) less than 2 were excluded - Analysis method
- GATK HaplotypeCaller -ERC GVCF (version 4.1.0.0)
The ploidy for variant call was set as follows:
Autosomes and pseudoautosomal regions (PARs): ploidy=2
Non-PARs on the X chromosome: ploidy=2 (female) and ploidy=1 (male)
Non-PARs on the Y chromosome: ploidy=1 (male) - Processed data type
