Summary for Patent: 7,507,800
Title:Diagnostic test kit for determining a predisposition for breast and ovarian cancer, materials and methods for such determination
Abstract: The present invention relates generally to the field of human genetics, and more specifically to the detection of a specific type of germline mutations in the BRCA1 gene, which will predispose to breast and ovarian cancer. In addition, the invention relates to the molecular genetic mechanism that may have mediated the genesis of these mutations, in particular the role of Alu repetitive DNA elements present in the intronic regions of BRCA1. The invention further relates to somatic mutations of this type in the BRCA1 gene in human breast and ovarian cancer, and their use in the diagnosis and prognosis of human breast and ovarian cancer. The invention more particularly relates to the screening of this type of BRCA1 mutations in human genomic DNA, which are useful for the diagnosis of inherited predisposition to breast and ovarian cancer.

Assignee: Rijksuniversiteit te Leiden (Leiden, NL)
Application Number:10/654,382
Patent Claims:1. A labeled probe for detecting a deletion of a stretch of nucleotides from a BRCA1 gene, wherein said deletion consists of: a. exon 22, b. nucleotides 1396-1662, c. exons 13 through 16, d. exon 13, e. an exon 22 deletion that starts in intron 21 and ends in intron 22, or f. an exon 13 deletion that starts in intron 12 and ends in intron 13 wherein the probe is a fusion product of two nucleic acid sequences adjacent to the deletion that is capable of detecting the deletion.

2. A diagnostic test kit for detecting a predisposition for breast and ovarian cancer, comprising a labeled probe for detecting a deletion of a stretch of nucleotides from a BRCA1 gene, wherein the labeled probe consists of: a. a sequence specific for detecting a deletion consisting of exon 22, b. a sequence specific for detecting a deletion consisting of nucleotides 1396-1662, c. a sequence specific for detecting a deletion consisting of exons 13 through 16, d. a sequence specific for detecting a deletion consisting of exon 13, e. a sequence specific for detecting a deletion consisting of an exon 22 deletion that starts in intron 21 and ends in intron 22, or f. a sequence specific for detecting a deletion consisting of an exon 13 deletion that starts in intron 12 and ends in intron 13 wherein the probe is a fusion product of two nucleic acid sequences adjacent to the deletion that is capable of detecting the deletion.

3. A diagnostic test kit according to claim 2, comprising at least two of a, b, c, and d.

4. A diagnostic test kit according to claim 2, comprising at least four of a, b, c, and d.

5. A diagnostic test kit for detecting a predisposition for breast and ovarian cancer, comprising labeled probes for detecting in a sample the presence of a nucleic acid derived from a BRCA1 gene having a deletion, wherein the probes comprise at least two of the following: a. a labeled sequence specific for either side of a deletion consisting of exon 22, b. a labeled sequence specific for either side of a deletion consisting of nucleotides 1396-1662, c. a labeled sequence specific for either side of a deletion consisting of exons 13 through 16, d. a labeled sequence specific for either side of a deletion consisting of exon 13, e. a labeled sequence specific for a deletion consisting of an exon 22 deletion that starts in intron 21 and ends in intron 22, or f. a labeled sequence specific for a deletion consisting of an exon 13 deletion that starts in intron 12 and ends in intron 13.

6. A diagnostic test kit according to claim 2, comprising at least three of a, b, c, and d.

7. A diagnostic test kit according to claim 2, comprising at least four of a, b, c, and d.
