Genes affected
CADM2 (HGNC:29849): (cell adhesion molecule 2) This gene encodes a member of the synaptic cell adhesion molecule 1 (SynCAM) family which belongs to the immunoglobulin (Ig) superfamily. The encoded protein has three Ig-like domains and a cytosolic protein 4.1 binding site near the C-terminus. Proteins belonging to the protein 4.1 family crosslink spectrin and interact with other cytoskeletal proteins. Multiple transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2024The c.748T>G (p.C250G) alteration is located in exon 6 (coding exon 6) of the CADM2 gene. This alteration results from a T to G substitution at nucleotide position 748, causing the cysteine (C) at amino acid position 250 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
