High Resolution Melting Analysis is Very Useful to Identify Breast Cancer Type 1 Susceptibility Protein (BRCA1) c.4964_4982del19 (rs80359876) Founder Calabrian Pathogenic Variant on Peripheral Blood and Buccal Swab DNA

Introduction Detection of pathogenic variants in hereditary breast and ovarian cancer-related breast cancer type 1 and type 2 susceptibility proteins (BRCA1/2) genes is an effective strategy in cancer prevention and treatment. Some ethnic and geographical regions show different BRCA1/2 mutation spectrum and prevalence. In Italy, elucidation of founder effect in BRCA1/2 genes can have an impact on the management of hereditary cancer families on a healthcare system level, making genetic testing more affordable and cost effective in certain regions.
