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.7402C>T (p.R2468W) alteration is located in exon 31 (coding exon 31) of the TENM1 gene. This alteration results from a C to T substitution at nucleotide position 7402, causing the arginine (R) at amino acid position 2468 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
