Single Nucleotide Polymorphisms in Brca1 and Cancer Risk
The invention provides methods for identifying mutations, such as single nucleotide polymorphisms (SNPs), within breast and ovarian cancer associated genes that modify the binding efficacy of micro RNAs (miRNAs). In a preferred embodiment, methods of the invention identify a SNP that decreases expression of the BRCA1 gene by increasing or decreasing the binding efficacy of at least one miRNA. Alteration of miRNA binding to BRCA1 by the introduction of SNPs within miRNA binding sites modulates or decreases BRCA1 expression, ultimately leading to the unregulated cell proliferation of a breast or ovarian cancer cells.
