Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to do a follow-up survey of all individuals with hereditary hypophosphatemia in Norway, focusing on manifestations in childhood and adolescence. The investigators also want to study phenotype-genotype associations, and look for new genes, in all forms of hereditary hypo and hyperphosphatemia.
