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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.499G>A (p.G167R) alteration is located in exon 3 (coding exon 3) of the TACC1 gene. This alteration results from a G to A substitution at nucleotide position 499, causing the glycine (G) at amino acid position 167 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
