The gene panel results were negative for several hypophosphatemia-related genes OCRL, ALPL, CLCN5, CYP27B1, CYP2R1, DMP1, ENPP1, FAH, FGF23, KL, PHEX, SLC34A1, SLC34A3, and VDR genes (Blueprint Genetics, Finland and Center for Genomics and Transcriptomics, Germany). This evidence concerns the gene PHEX and hypophosphatemia.
