Dominantly inherited PFBC is associated with mutations in four genes: solute carrier 20 member 2 (SLC20A2) [15], xenotropic and polytropic retrovirus receptor 1 (XPR1) [16], platelet-derived growth factor B (PDGFB) [17] and platelet-derived growth factor receptor B (PDGFRB) [18]. This evidence concerns the gene XPR1 and bilateral striopallidodentate calcinosis.
