CD300A (CD300a Molecule) is a Protein Coding gene. Diseases associated with CD300A include Kabuki Syndrome 1. Among its related pathways are Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell and Innate Immune System. GO annotations related to this gene include phosphatidylserine binding and signaling receptor activity. An important paralog of this gene is CD300C.This gene encodes a member of the CD300 glycoprotein family of cell surface proteins found on leukocytes involved in immune response signaling pathways. This gene is located on chromosome 17 in a cluster with all but one of the other family members. Multiple transcript variants encoding different isoforms have been found for this gene.
