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)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2023The c.998A>G (p.N333S) alteration is located in exon 5 (coding exon 5) of the CTGF gene. This alteration results from a A to G substitution at nucleotide position 998, causing the asparagine (N) at amino acid position 333 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
