Genes affected

TACC1 (HGNC:11522): (transforming acidic coiled-coil containing protein 1) This locus may represent a breast cancer candidate gene. It is located close to FGFR1 on a region of chromosome 8 that is amplified in some breast cancers. Several transcript variants encoding different isoforms have been found for this gene.

The c.635A>G (p.D212G) alteration is located in exon 3 (coding exon 3) of the TACC1 gene. This alteration results from a A to G substitution at nucleotide position 635, causing the aspartic acid (D) at amino acid position 212 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
