Detection, Prioritization And Analysis Of Variants Of Unknown Significance In Familial Breast Cancer Genes, Eddie A. Dovigi

Electronic Thesis and Dissertation Repository

Currently, Molecular Diagnostics Laboratories in Ontario sequence coding and adjacent intronic regions in BRCA1 and BRCA2 in patients with a family history of breast cancer. At LHSC it is estimated that ~15% of patients have BRCA1 or BRCA2 variants of clinical significance, and ~15-20% patients have variants of unknown clinical significance (VUS), while the remaining patients have variants of no clinical significance, making patient prognosis difficult to ascertain. To elucidate VUS and improve deleterious variant detection, my study has three aims, 1) assess the effects of VUS on splicing using bioinformatics and transfection assays; 2) investigate the limitations of BRCA1 …
