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]

The c.262G>A (p.D88N) alteration is located in exon 3 (coding exon 3) of the CADM3 gene. This alteration results from a G to A substitution at nucleotide position 262, causing the aspartic acid (D) at amino acid position 88 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
