<b>Results:</b><i>SRD5A2</i> rs9282858 (A49T) polymorphism showed a significant correlation with increased B</span>PH susceptibility under allele T vs.allele A genetic model (OR = 2.51, 95% CI = 1.29-4.88) in total analysis, and stratification analysis by ethnicity also revealed a similar association in Caucasian group under the same contrast.
We found statistically significant relationship between the SRD5A2 gene Ala49Thr (OR=2.3; CI 95%, 1.04-5.1; p=0.01<0.05) , but not the other polymorphisms, and B</span>PH.
The SRD5A2 polymorphisms A49T, V89L and R227Q, the androgen receptor CAG and GGN repeats and sex hormone status was investigated in men with prostate cancer (CaP) (n=89), benign prostate hyperplasia (n=45) and healthy military conscripts (n=223).
The enzyme is a target in pharmacological treatment of benign prostatic hyperplasia using specific inhibitors such as finasteride.Makridakis et al. have characterized the V89L and A49T polymorphisms in recombinant expression systems.
