Abstract excerpt
INTRODUCTION: Autosomal dominant hypophosphatemic rickets (ADHR) is caused by pathogenic variants in the fibroblast growth factor 23 (FGF23) gene, which plays a key role in the regulation of phosphorus metabolism. FGF23 has the RXXR motif recognized by furin, leading to cleavage between R179 and S180 and thereby inactivating the protein's function. Previously reported variants in FGF23 causing ADHR occurred only...
