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]

The c.5692G>A (p.G1898R) alteration is located in exon 26 (coding exon 26) of the TENM2 gene. This alteration results from a G to A substitution at nucleotide position 5692, causing the glycine (G) at amino acid position 1898 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
