CD1a

CD1A (CD1a Molecule) is a Protein Coding gene. Diseases associated with CD1A include Langerhans Cell Histiocytosis and Histiocytosis. Among its related pathways are Innate Immune System and Class I MHC mediated antigen processing and presentation. Gene Ontology (GO) annotations related to this gene include beta-2-microglobulin binding and endogenous lipid antigen binding. An important paralog of this gene is CD1B.
