...Feinberg. "The BRCA1 and BRCA2 genes implicated in breast and ovarian cancers are great examples, but they are applicable only to a small percentage -- less than one percent -- of women." But while the troublesome BRCA1 and BRCA2 genes stem from changes in the sequence of the DNA itself, the problems with ...
