Technique allows researchers to toggle on individual genes that regulate cell growth, development and function.
Folliculin gene defects are implicated in some forms of infertility, certain cancers and other cell growth disorders.
An analysis of nearly 4,000 mutations deliberately engineered into the BRCA1 gene will immediately benefit people undergoing genetic testing for breast or ovarian cancer risk.
Findings on nearly 4,000 BRCA1 mutations will be immediately useful to many patients with previously inconclusive genetic test results.
