Genes affected
CCN1 (HGNC:2654): (cellular communication network factor 1) The secreted protein encoded by this gene is growth factor-inducible and promotes the adhesion of endothelial cells. The encoded protein interacts with several integrins and with heparan sulfate proteoglycan. This protein also plays a role in cell proliferation, differentiation, angiogenesis, apoptosis, and extracellular matrix formation. [provided by RefSeq, Sep 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2023The c.754A>G (p.T252A) alteration is located in exon 4 (coding exon 4) of the CYR61 gene. This alteration results from a A to G substitution at nucleotide position 754, causing the threonine (T) at amino acid position 252 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
