ALOX5AP (Arachidonate 5-Lipoxygenase-Activating Protein): ALOX5AP is a gene that encodes a protein involved in activating the enzyme arachidonate 5-lipoxygenase (ALOX5). This enzyme plays a crucial role in metabolizing arachidonic acid and producing leukotrienes, which are important inflammatory mediators. Variations in ALOX5AP have been associated with cardiovascular diseases and asthma.
