Despite the thorough analysis, no known pathogenic variants were found in genes typically associated with Fahr’s syndrome (e.g., XRP1, PDGFRB, JAM2, PDGFB, SLC20A2, or MYORG) or pseudohypoparathyroidism (e.g., GNAS, STX16, or GNASAS1). The gene discussed is GNAS; the disease is pseudohypoparathyroidism.
