Genes affected

TENM1 (HGNC:8117): (teneurin transmembrane protein 1) The protein encoded by this gene belongs to the tenascin family and teneurin subfamily. It is expressed in the neurons and may function as a cellular signal transducer. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene.

The c.7251T>G (p.N2417K) alteration is located in exon 30 (coding exon 30) of the TENM1 gene. This alteration results from a T to G substitution at nucleotide position 7251, causing the asparagine (N) at amino acid position 2417 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
