Genes affected

XPR1 (HGNC:12827): (xenotropic and polytropic retrovirus receptor 1) The protein encoded by this gene is a receptor for the xenotropic and polytropic classes of murine leukemia viruses. The encoded protein is involved in phosphate homeostasis by mediating phosphate export from the cell. Defects in this gene have been associated with idiopathic basal ganglia calcification-6.
