Methods of detecting prostate cancer using BAP28-related biallelic markers
The present invention is directed to BAP28 polypeptides. BAP28 cDNA sequences encoding BAP28 polypeptides, to the genomic DNA sequence of the BAP28 gene as well as to regulatory regions located at the 5′- and 3′-ends of the BAP28 coding region. The invention also deals with antibodies directed specifically against such polypeptides that are useful as diagnostic reagents. The invention further encompasses biallelic markers of the BAP28 gene useful in genetic analysis. The invention concerns an association of the BAP28-related biallelic markers with prostate cancer. Therefore, the invention contemplates the diagnostic and treatment methods of prostate cancer.
1. A method of detecting a risk of developing prostate cancer in an individual, comprising:
a) genotyping a biological sample from the individual to determine the identity of a combination of three BAP28-related biallelic markers (BM) or the complements thereof, said combination of three BAP28-related biallelic markers being the allele combination of TAT at biallelic markers A53, A51 and A34; and
b) detecting the presence of the allele combination of TAT at biallelic markers A53, A51 and A34 in said biological sample as indicative of a risk of developing prostate cancer in said individual, said biallelic markers being located at the following positions: nucleotide 402 in SEQ ID NO: 26 (A53); nucleotide 278 in SEQ ID NO: 24 (A51); and nucleotide 71993 in SEQ ID NO: 1 (A34), wherein the T of the A34 biallelic marker is the complement of the A depicted at nucleotide 71993 in SEQ ID NO: 1.
