A recurrent pathogenic BRCA2 exon 5–11 duplication in the Christian Arab population in Israel

Germline pathogenic variants (PVs) in BRCA1/BRCA2 are well-established risk factors for breast cancer (BC) and/or ovarian cancer (OC). Founder PVs have been described in BRCA1/ BRCA2 in several genetic isolates. The Christian Arab population in the Middle East is a relatively isolated ethnic group, yet founder, or recurrent BRCA1/BRCA2 PVs have not been reported in this population. In this study we describe PVs detected in cancer susceptibility...
