Specific ablation of mouse Fam20C in cells expressing type I collagen leads to skeletal defects and hypophosphatemia

Abstract FAM20C mutations in humans cause Raine syndrome and our previous studies showed that global inactivation of mouse Fam20C led to bone and dental defects. By crossbreeding 2.3 kb Col 1a1-Cre mice with Fam20C flox/flox mice, we created 2.3 kb Col 1a1-Cre;Fam20C foxl/flox (cKO) mice, in which...
