  1. aQuality standard (QS) ‘10 × ’ represents the percentage of locations with coverage depth greater than 10-fold on the targeted exon. Accordingly, ‘10× ≥95%’ means the pre-defined percentage (that is, ‘10 × ’) is 95% or above. (‘20 × ’ has a similar definition). bThe four-digit (two-digit) percentage is equal to the number of HLA calls at four-digit (two-digit) resolution without ambiguity divided by the total number of alleles.
