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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.874

The c.569G>A (p.G190E) alteration is located in exon 5 (coding exon 5) of the CADM3 gene. This alteration results from a G to A substitution at nucleotide position 569, causing the glycine (G) at amino acid position 190 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
