Core Tip

Core Tip: This is the first study on referred patients with breast and/or ovarian cancer and subjects at high hereditary risk for germline pathogenic variant testing among ethnic Lebanese Arab women. The prevalence of pathogenic variants was 8.63% in patients with breast cancer and 15.1% in patients with ovarian cancer. Among the relatives of patients with breast cancer susceptibility gene (BRCA) 1/2 pathogenic variants, 31% tested positive for the same variant, while 5.3% of subjects who tested positive due to a family history of breast cancer had a BRCA pathogenic variant. The results of this study support the hypothesis that the c.131G>T nucleotide change is a founder pathogenic variant in this population.
