Abstract excerpt
BACKGROUND: Hereditary breast and ovarian cancer syndrome (HBOC) and Lynch syndrome (LS), the most common inherited cancer syndromes, are attributed to a single heterozygous pathogenic variant (PV) in BRCA1/2 or in a DNA MMR gene, respectively. Little is known about the phenotype in double heterozygotes who carry PVs in both genes. METHODS: Carriers of double-PVs in any DNA MMR gene and BRCA1/2 attending one of...
