Myriad Genetics other research news

Duke University researchers and collaborators reported in Nature Genetics that the BRCA2 breast cancer gene may be involved in fewer cases of inherited breast cancer than previously thought. MYGN is developing diagnostics based on the gene.

Mutations of the first breast cancer gene identified, BRCA1, account for about half of the 5-10 percent of breast cancers that are inherited. In a study of 49 Canadian families with a history of breast cancer unlikely to be due to mutations in the BRCA1 gene, researchers had expected to find a large number of BRCA2 mutations. However, they found only eight, leaving open the possibility that other, undiscovered, genes are linked to breast cancer. ...
