New mutations have been found in the BRCA1 gene. The mutations are located at nucleotide numbers 421-2, 815, 903, 926, 1506, 2034, 2428, 3888, 3904, 4164, 4643, 5053, 5150, 5210, or 5396+40 of the gene sequence of BRCA1. A process for identifying a sequence variation in a BRCA1 polynucleotide sequence is disclosed. The identification process includes allele specific sequence-based assays of known sequence variations. The methods can be used for efficient, and accurate detection of a mutation in a test BRCA1 gene sample.

Cancer susceptibility mutations of BRCA1

New mutations have been found in the BRCA2 gene. The mutations are located at nucleotide numbers 2192, 3772, 5193, 5374, 6495 or 6909 of the published nucleotide sequence of BRCA2 gene. A process for identifying a sequence variation in a BRCA2 polynucleotide sequence is disclosed. The identification process includes allele specific sequence-based assays of known sequence variations. The methods can be used for efficient, and accurate detection of a mutation in a test BRCA2 gene sample.

Cancer susceptibility mutations of BRCA2

A step-wise integrated process for identifying sequence variations in polynucleotide sequences is disclosed. The identification process is composed of three stages, including allele specific hybridization assays of known sequence variations (Stage I), sequence variation locating assays (Stage II), and direct sequencing (Stage III). The methods can be used for efficient and accurate detection of mutations in any test gene sample.

Method for identifying variations in polynucleotide sequences

A new mutation has been found in the BRCA1 gene. The mutation is a two base pair deletion at nucleotides 3888 and 3889 of the published cDNA sequence of BRCA1 (GENBANK ACCESSION NO:U14680). The invention provides a method for diagnosing persons at risk of developing breast or ovarian cancer. The invention also provides a further tool with which to characterize tumors.
