HLA-B5701

Human Leukocyte Antigens (HLAs) are proteins that play a crucial role in immune response regulation. The HLA-B5701 allele encodes a specific form of the HLA-B protein, which has been shown to be highly relevant in the metabolism and response to certain medications. The primary drug implicated is abacavir, a nucleoside reverse transcriptase inhibitor used in the treatment of HIV/AIDS.
