In another report, Jakubowska et al. [29] identified BRCA2 gene mutations (three frameshifts and three sequence variants) in 29 Polish families with an aggregation of at least one female breast and one male stomach cancer and observed significant differences between the incidence of BRCA2 mutations in the breast/male stomach cancer families when this group was compared to the breast/ovarian cancer families (p < 0.025). Here, BRCA2 is linked to gastric neoplasm.
