  • The correct classification of BRCA1 missense variants presents a challenge to provide accurate genetic counseling and targeted cancer therapy.
  • To improve the classification of these alterations, we propose an integrated approach: clinical data, protein structure, in silico analyses, and population allele frequency followed by HDR assay and quantitative infrared western blot analyses.
  • This approach may also be used to assess additional missense VUS in other Hereditary Breast and Ovarian Cancer genes involved in the HDR pathway.
