Genes affected

CYP17A1 (HGNC:2593): (cytochrome P450 family 17 subfamily A member 1) This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum. It has both 17alpha-hydroxylase and 17,20-lyase activities and is a key enzyme in the steroidogenic pathway that produces progestins, mineralocorticoids, glucocorticoids, androgens, and estrogens. Mutations in this gene are associated with isolated steroid-17 alpha-hydroxylase deficiency, 17-alpha-hydroxylase/17,20-lyase deficiency, pseudohermaphroditism, and adrenal hyperplasia.

WBP1L (HGNC:23510): (WW domain binding protein 1 like) Predicted to enable ubiquitin protein ligase binding activity. Predicted to act upstream of or within CXCL12-activated CXCR4 signaling pathway; hemopoiesis; and positive regulation of protein ubiquitination. Predicted to be integral component of membrane.
