  • Pipeline errors: Errors in proband assembly caused by phasing, read correction, or assembly mistakes. Coverage errors: Errors caused by low depth of coverage in either the proband or paternal capture. Sequence complexity errors: Homopolymer or simple repeat length discrepancies between the proband and paternal assemblies. Bionano discrepancies: Number of missing DLE-1 sites in MHC assembly. HLA sequence errors: Number of differences compared to Illumina HLA typing data. Microarray errors: Number of positions discordant with microarray typing after manual review. Total errors: Total errors across all sources. Assembly accuracy: For PGF, COX, and proband samples, the total accuracy of MHC assembly. For AFA, the accuracy across positions was queried by Bionano, HLA typing, and microarray genotyping.
