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.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.598 is higher than 0.05.
