Genes affected

TENM2 (HGNC:29943): (teneurin transmembrane protein 2) Enables cell adhesion molecule binding activity and signaling receptor binding activity. Involved in several processes, including calcium-mediated signaling using intracellular calcium source; heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules; and retrograde trans-synaptic signaling by trans-synaptic protein complex. Located in cell-cell junction and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• BS2: High AC in GnomAdExome4 at 12 AD gene.

Collection Method: clinical testing

The c.439C>G (p.R147G) alteration is located in exon 2 (coding exon 2) of the TENM2 gene. This alteration results from a C to G substitution at nucleotide position 439, causing the arginine (R) at amino acid position 147 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
