Genes affected

CADM3 (HGNC:17601): (cell adhesion molecule 3) The protein encoded by this gene is a calcium-independent cell-cell adhesion protein that can form homodimers or heterodimers with other nectin proteins. The encoded protein has both homophilic and heterophilic cell-cell adhesion activity. This gene is reported to be a tumor suppressor gene. [provided by RefSeq, Oct 2016]

CADM3 links:

AIM2 (HGNC:357): (absent in melanoma 2) AIM2 is a member of the IFI20X /IFI16 family. It plays a putative role in tumorigenic reversion and may control cell proliferation. Interferon-gamma induces expression of AIM2. [provided by RefSeq, Jul 2008]

Ambry Genetics

Feb 28, 2024

The c.73A>C (p.N25H) alteration is located in exon 1 (coding exon 1) of the CADM3 gene. This alteration results from a A to C substitution at nucleotide position 73, causing the asparagine (N) at amino acid position 25 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
