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]

Jun 18, 2021

The c.156C>G (p.D52E) alteration is located in exon 2 (coding exon 2) of the CTGF gene. This alteration results from a C to G substitution at nucleotide position 156, causing the aspartic acid (D) at amino acid position 52 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
