Men who inherit a mutation in the BRCA2 gene carry a 6% risk of developing breast cancer by the age of 70. The proportion of male breast cancers attributable to BRCA mutations has not yet been determined with accuracy. We studied a series of 14 male breast cancer patients, unselected for ...
We observed a highly significant association of carrying a pathogenic BRCA2 mutation with high tumor grade ( P <0.001) and a weak association with positive lymph nodes ( P <0.02). Of the 97 BRCA2 -negative MBC cases, we identified one PALB2 mutation with confirmed pathogenicity and one ...
BRCA1 mutation positive women in one study from Prague area [51]. The BRCA1 c.3700_3704del5 mutation is also frequent mutation in Germany [99]. Three BRCA1 Czech founder mutations (c.181T>G, c.3700_3704del5, and c.5266dupC) account for approximately 9%, 13% and 44% of the ...
However, none of these families was positive for theBRCA1 orBRCA2 mutation. Histopathologically, we observed a prevalence of histological grade 3 inBRCA2-associated familial breast cancers, because of nuclear atypia, structural atypia and mitotic activity. It is suggested thatBRCA2 may play a ...

Mutations in BRCA2 have also been linked to male breast cancer (Easton et al. 1997; Couch et al. 1996). Unlike many genes that contain mutation "hot-spots," genetic variants are dispersed throughout the BRCA2 gene. Approximately 83 of 684 genetic variants recorded in BRCA2 occur in ...
Mutation carriers were indistinguishable from noncarriers on the basis of median (range) age at lymphoma diagnosis (12.8 [6.0-17.7] years vs 13.5 [1.1-22.7] years; P = .40). All 8 survivors of non–Hodgkin lymphoma with BRCA2 mutations were male. In a comparison with controls without...
We classified men who had at least one first- or second-degree relative diagnosed with PCa as having a positive PCa family history, and assessed trends in risks according to the number of affected relatives. We investigated differences in risk by mutation position using prespecified definitions of...
