11. Certain variants of this gene increase the risk for decreased histocompatibility characteristic of type 1. 12. In humans, the tapasin gene lies within the major histocompatibility complex on chromosome 6. 13. The gene is located within the major histocompatibility complex ( MHC ) on chromosome 6. 14. The N-terminal domain contains regions involved in Major Histocompatibility Complex class II association. 15. In 1984, the American Society for Histocompatibility and Immunogenetics named an award in her honor. 16. More than 30 genes have been discovered in a gene complex called the major histocompatibility complex. 17. Iowa Regional Histocompatibility and Immunogenetics Laboratory. 18. The AIF1 gene is located within a segment of the major histocompatibility complex class III region. 19. The haplotype can be written in an extended form covering the major histocompatibility loci as follows: 20. Minor histocompatibility antigens, a conceptually similar antigen class are also correctly identified by MHC binding algorithms.
