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. [provided by RefSeq, Sep 2009]

TENM1 links:

STAG2 (HGNC:11355): (STAG2 cohesin complex component) The protein encoded by this gene is a subunit of the cohesin complex, which regulates the separation of sister chromatids during cell division. Targeted inactivation of this gene results in chromatid cohesion defects and aneuploidy, suggesting that genetic disruption of cohesin is a cause of aneuploidy in human cancer. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]

The c.7667G>A (p.R2556Q) alteration is located in exon 32 (coding exon 32) of the TENM1 gene. This alteration results from a G to A substitution at nucleotide position 7667, causing the arginine (R) at amino acid position 2556 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
