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.520G>A (p.V174M) alteration is located in exon 3 (coding exon 3) of the CTGF gene. This alteration results from a G to A substitution at nucleotide position 520, causing the valine (V) at amino acid position 174 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
