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 GeneticsAug 04, 2023The c.704C>T (p.P235L) alteration is located in exon 3 (coding exon 3) of the TACC1 gene. This alteration results from a C to T substitution at nucleotide position 704, causing the proline (P) at amino acid position 235 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
