Abstract: A method and system for typing major histocompatibility complex (MHC) alleles. The method includes receiving a set of exon-resolution identifiers for an allele pair associated with an MHC gene. An exon-resolution identifier of the set of exon-resolution identifiers for a corresponding allele of the allele pair describes an allele group, a specific allele protein, and exon region information for the corresponding allele.
