Osteoglycin(also Mimecan), encoded by the OGN gene is a human protein.[1]

This gene encodes a protein which induces ectopic bone formation in conjunction with transforming growth factor beta. This protein is a small proteoglycan which contains tandem leucine-rich repeats (LRR). The gene expresses three transcript variants.[1]

The level of expression of this gene has been correlated with enlarged hearts and more specifically left ventricular hypertrophy.[2][3]
