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]

Ambry Genetics

Nov 09, 2022

The c.5A>G (p.Q2R) alteration is located in exon 1 (coding exon 1) of the NOV gene. This alteration results from a A to G substitution at nucleotide position 5, causing the glutamine (Q) at amino acid position 2 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
