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

Sep 01, 2024

The c.185C>T (p.S62L) alteration is located in exon 2 (coding exon 2) of the NOV gene. This alteration results from a C to T substitution at nucleotide position 185, causing the serine (S) at amino acid position 62 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
