HLAD QA1
Description
The HLA-DQA1 gene, located on chromosome 6, plays a crucial role in the immune system by encoding a protein component of the MHC class II molecule. This molecule is responsible for presenting antigens to T lymphocytes, triggering an immune response. HLA-DQA1 exhibits significant genetic variability, with numerous alleles contributing to diverse immune responses and susceptibility to certain diseases.
