HLA-A9 (A9) is a broad antigen HLA

Human leukocyte antigen

The human leukocyte antigen system is the name of the major histocompatibility complex in humans. The super locus contains a large number of genes related to immune system function in humans. This group of genes resides on chromosome 6, and encodes cell-surface antigen-presenting proteins and...

HLA-A

HLA-A are a group of human leukocyte antigens that are encoded by the HLA-A locus on human chromosome 6p. The HLA genes constitute a large subset of the Major histocompatibility complex of humans. HLA-A is a component of certain MHC class I cell surface receptor isoforms that resides on the...

Serotype or serovar refers to distinct variations within a subspecies of bacteria or viruses. These microorganisms, viruses, or cells are classified together based on their cell surface antigens...

HLA-A23

HLA-A23 is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α23 subset of HLA-A α-chains. For A23, the alpha, "A", chain are encoded by the HLA-A*23 allele group and the β-chain are encoded by B2M locus. This group currently...

HLA-A24

HLA-A24 is a human leukocyte antigen serotype within HLA-A serotype group. The serotype is determined by the antibody recognition of α24 subset of HLA-A α-chains. For A24, the alpha, "A", chain are encoded by the HLA-A*24 allele group and the β-chain are encoded by B2M locus. This group currently...

 serotypes. A*2402 appears to have evolved from A*23 alleles by a process of gene conversion. The A23 is more common in Africa and regions proximal to Africa. A24 is at very high frequencies in Austronesia and certain indigenous peoples of the Arctic, North America, South America and West Pacific Rim. While it is common over most of Eurasia, it is found at low abundance in NW Europe. A24 appears to have been carried by the first colonizers of South Eastern Asia.
