The CYP17 gene encodes the cytochrome P450c17โฃ enzyme, which functions at 2 different points in the steroid biosynthesis pathway, and is considered a candidate susceptibility gene for endocrine-related tumors. A T to C substitution polymorphism exists in the 5 promoter region of this gene, and creat
CYP17 encodes the enzyme cytochrome P-450c17โฃ, which mediates both 17โฃ-hydroxylase and 17,20-lyase in the steroid biosynthesis pathway. A polymorphism in the 5 promoter region of the CYP17 gene has been described. Steroid hormones, especially androgens, are believed to play a key role in the etiolog
## Abstract Because androgens likely play a key role in prostate growth and prostate cancer development, variants of genes involved in androgen biosynthesis may be related to prostate cancer risk. The enzyme P450c17ฮฑ, encoded by the __CYP17__ gene, catalyzes the conversion of progesterone and pregn
