The protein encoded by this gene is a proteoglycan that may function as a neural growth and differentiation factor. Several transcript variants encoding different isoforms have been found for this gene.CSPG5 (Chondroitin Sulfate Proteoglycan 5) is a Protein Coding gene. Diseases associated with CSPG5 include Spontaneous Ocular Nystagmus and Kabuki Syndrome 1. Among its related pathways are Chondroitin sulfate/dermatan sulfate metabolism and Glycosaminoglycan metabolism. GO annotations related to this gene include growth factor activity.
