NCIt related terms : BRCA1;
NCIt definition : A mutation that is typically a heritable, permanent change in the nucleotide sequence
of the BRCA1 gene. Single nucleotide substitutions and small deletions or insertions
(1-20 bases) account for the majority of mutations in the BRCA1 gene. Approximately
75% of these alterations result in a truncated form of the breast cancer type 1 susceptibility
protein. Mutations in the BRCA1 gene predispose individuals to breast and ovarian
cancers.;
