Genes affected
CCN3 (HGNC:7885): (cellular communication network factor 3) The protein encoded by this gene is a small secreted cysteine-rich protein and a member of the CCN family of regulatory proteins. CNN family proteins associate with the extracellular matrix and play an important role in cardiovascular and skeletal development, fibrosis and cancer development. [provided by RefSeq, Feb 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2023The c.431G>C (p.C144S) alteration is located in exon 3 (coding exon 3) of the NOV gene. This alteration results from a G to C substitution at nucleotide position 431, causing the cysteine (C) at amino acid position 144 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
