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 GeneticsApr 06, 2023The c.891G>C (p.R297S) alteration is located in exon 5 (coding exon 5) of the CYR61 gene. This alteration results from a G to C substitution at nucleotide position 891, causing the arginine (R) at amino acid position 297 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
