High incidence of 4153delA BRCA1 gene mutations in Lithuanian breast- and breast-ovarian cancer families.

Abstract excerpt

BRCA1 and BRCA2 gene mutations confer a high lifetime risk to breast and ovarian cancers. We have screened cancer patients from 13 families with at least three breast and/or ovarian cancers from Lithuania for 5382insC, C61G and 4153delA BRCA1 gene mutations. One of three mutations was found in 9 of the 13 studied families (69%). 4153delA was the most frequently detected and accounted for 56% of all identified...
