For example, a project entitled “LOCALIZATION OF X-LINKED HYPOPHOSPHATEMIC RICKETS GENE” (APPLICATION ID = “3087091”), has reported two publications, “Mutational analysis and genotype-phenotype correlation of the PHEX gene in X-linked hypophosphatemic rickets.” (PMID: 11502829) and “Mutational analysis of the PEX gene in patients with X-linked hypophosphatemic rickets.” (PMID: 9106524) These two publications specifically reported their investigation on genes for X-linked hypophosphatemic rickets. This evidence concerns the gene PHEX and X-linked hypophosphatemic rickets.
