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.5819G>A (p.R1940H) alteration is located in exon 27 (coding exon 27) of the TENM2 gene. This alteration results from a G to A substitution at nucleotide position 5819, causing the arginine (R) at amino acid position 1940 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
