Genes affected

TACC2 (HGNC:11523): (transforming acidic coiled-coil containing protein 2) Transforming acidic coiled-coil proteins are a conserved family of centrosome- and microtubule-interacting proteins that are implicated in cancer. This gene encodes a protein that concentrates at centrosomes throughout the cell cycle. This gene lies within a chromosomal region associated with tumorigenesis. Expression of this gene is induced by erythropoietin and is thought to affect the progression of breast tumors. Several transcript variants encoding different isoforms have been found for this gene.

Ambry Genetics

Nov 21, 2023

The c.266G>A (p.G89E) alteration is located in exon 4 (coding exon 3) of the TACC2 gene. This alteration results from a G to A substitution at nucleotide position 266, causing the glycine (G) at amino acid position 89 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
