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]

The c.112G>C (p.E38Q) alteration is located in exon 2 (coding exon 2) of the CTGF gene. This alteration results from a G to C substitution at nucleotide position 112, causing the glutamic acid (E) at amino acid position 38 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
