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.7634A>T (p.D2545V) alteration is located in exon 32 (coding exon 32) of the TENM1 gene. This alteration results from a A to T substitution at nucleotide position 7634, causing the aspartic acid (D) at amino acid position 2545 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
