Abstract : Since the last annual report, the BRCA2 gene was cloned by our collaborator on this grant. We identified the complete BRCA2 sequence which encodes a protein of 3,418 amino acids. Due to the successful completion of several of the aims, we added additional goals. We have identified predisposing mutations in six of our families and a polymorphism in a seventh. We are continuing to screen for mutations in our additional families using SSCP. Now that the gene has been isolated and mutations are being identified rapidly, we are constructing a database of haplotypes of mutations. In a collaborative project, we will examine common mutations to investigate mutation origin.
