Genes affected
CCN2 (HGNC:2500): (cellular communication network factor 2) The protein encoded by this gene is a mitogen that is secreted by vascular endothelial cells. The encoded protein plays a role in chondrocyte proliferation and differentiation, cell adhesion in many cell types, and is related to platelet-derived growth factor. Certain polymorphisms in this gene have been linked with a higher incidence of systemic sclerosis. [provided by RefSeq, Nov 2009]
LINC01013 (HGNC:48987): (long intergenic non-protein coding RNA 1013)
