Genomic sequence of the purH gene and purH-related biallelic markers
View Patent ↗The invention concerns the genomic sequence of the purH gene. The invention also concerns biallelic markers of a purH gene and the association established between these markers and cancer, particularly prostate cancer. The invention provides means to determine the predisposition of individuals to cancer as well as means for the diagnosis of cancer and for the prognosis/detection of an eventual treatment response to agents acting on cancer.
1. A method of determining whether an individual is at an increased risk for developing prostate cancer comprising the steps of:
(a) obtaining a biological sample comprising a nucleic acid from said individual;
(b) determining the identity of a biallelic marker at position 22906 of SEQ ID NO: 1 and 31250 of SEQ ID NO: 1 within said biological sample; and
(c) evaluating whether an individual is at increased risk of prostate cancer; wherein the presence of both an A at position 22906 of SEQ ID NO: 1 and a G at position 31250 of SEQ ID NO: 1 is indicative of an increased risk for developing prostate cancer.
2. The method according to claim 1 , further comprising the step of amplifying a portion of said purH gene comprising said biallelic marker prior to determining the identity of said nucleotide.
3. The method according to claim 2 , wherein said amplifying is performed by PCR.
4. The method according to claim 1 , wherein said nucleotide is determined by performing a microsequencing assay.
5. The method according to claim 1 , wherein said nucleotide is determined by performing a hybridization assay.
6. The method according to claim 1 , wherein said nucleotide is determined by performing a sequencing assay.
