HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]

Each person carries 2 alleles of each of the 3 class-I genes, (HLA-A, HLA-B and HLA-C), and so can express six different types of MHC-I (see figure). In the class-II locus, each person inherits a pair of HLA-DP genes (DPA1 and DPB1, which encode α and β chains), a couple of genes HLA-DQ ( DQA1 and DQB1 , for α and β chains), one gene HLA ...
HLA, the human form of the major histocompatibility complex (MHC), is located on chromosome 6 at 6p21.3. [11] Individuals inherit two different HLA haplotypes, one from each parent, each containing more than 200 genes relevant to helping the immune system recognize foreign invaders. These genes include MHC class I and class II cell-surface ...

The frequency of *0101 is 1000 times more abundant than *0103, or 99.9% of the time you have identified the correct allele with the serotype. The false negative rate for HLA-A1 serotype is 1% and the giving the HLA-A1 serotyping a specificity of 98.9% for the A1*0101 allele. Increasing confidence of Interpretation
There are four commonly encountered DQA1 alleles: DQA1*0101, *0102, *0103, *0104. These alleles are always found in haplotypes with HLA-DQB1*05 and HLA-DQB1*06 . DQ1 is a serotype, rare among serotypes for human class II antigens, in that the antibodies to DQ1 react to the alpha chain of HLA DQ, these DQA1 allele gene products.
HLA-A1 (A1) is a human leukocyte antigen serotype within HLA-A "A" serotype group. The serotype is determined by the antibody recognition of α 1 subset of HLA-A α-chains. For A1, the alpha "A" chain are encoded by the HLA-A *01 allele group and the β-chain are encoded by B2M locus. [1] This group currently is dominated by A*01:01.
