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.7342G>A (p.V2448I) alteration is located in exon 31 (coding exon 31) of the TENM1 gene. This alteration results from a G to A substitution at nucleotide position 7342, causing the valine (V) at amino acid position 2448 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
