We identified 17 BRCA1 mutations in 86 Austrian breast and ovarian cancer families (20%) that were screened for mutations by denaturing high-performance liquid chromatography (DHPLC) and the protein truncation test (PTT). Eleven distinct mutations were detected, 4 of them (962del4, 2795del4, 3135del

β¦ Synopsis
Duchenne muscular dystrophy (DMD) is an X-linked degenerative disorder of muscle, caused by gross rearrangements by the dystrophin gene in two-thirds of cases. The remaining one-third of patients may carry more subtle mutations that are difficult to detect because of the large size and complexity of this gene (Roberts et al., 1994).

BRCA1 is a tumour suppressor gene located on chromosome band 17q21. It is estimated that mutations in the BRCA1 gene account for approximately 45% of the breast cancer families and almost all of the breast/ovarian cancer families.

The cloning of the breast and ovarian cancer susceptibility gene, BRCA1, allows direct estimation of the proportion of these cancers in the general population which can be attributed to germline mutations in this gene. We have used a combination of SSCP, heteroduplex analysis, and chemical cleavage
