Scientific Evidence
Understanding the Data
- SNP: A specific genetic marker relevant to this trait (e.g., rs2588978)
- Genotype: Your genetic makeup at the given SNP location (e.g., CC)
- Variant allele: The alternative DNA sequence at the SNP site
- Variant allele frequency: Percentage of population carrying this variant
- Variant found: Whether the variant was detected in your DNA file
HLA-DRA GeneCards
HLA-DRA is one of the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha and a beta chain, both anchored in the membrane. This molecule is expressed on the surface of various antigen presenting cells such as B lymphocytes, dendritic cells, and monocytes/macrophages, and plays a central role in the immune system and response by presenting peptides derived from extracellular proteins, in particular, pathogen-derived peptides to T cells. The alpha chain is approximately 33-35 kDa and its gene contains 5 exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, and exon 4 encodes the transmembrane domain and the cytoplasmic tail. DRA does not have polymorphisms in the peptide binding part and acts as the sole alpha chain for DRB1, DRB3, DRB4 and DRB5. [provided by RefSeq, Aug 2020]
