Although, a functional rationale for influence of polymorphism D85Y in gene UGT2B15 on prostate cancer (PCa) exists (different V(max) of enzyme), conflicting results have been reported.


DNA from 178 controls and 206 PCa patients with known Gleason score were genotyped using a newly developed RFLP assay, which allowed the detection of both alleles in an individual after single PCR amplification.



16% DD, 52% DY; PCa patients: 23% DD, 49% DY. Subgroups of PCa: well differentiated: 11% DD, 37% DY; moderately differentiated: 22% DD, 50% DY; poorly differentiated: 34% DD, 50% DY. Correlation was confirmed between Gleason score and number of D alleles (P = 0.018) and persisted after age adjustment. When comparing controls to patients with a Gleason score of 7 or more, difference for the frequency of homozygosity DD was significant between the groups (P = 0.032, OR = 2.04).


Polymorphism D85Y in gene UGT2B15 correlates with differentiation of PCa.
