Plasma analysis of ~5 week old kl203X mice.

Values are expressed as mean±SEM.aPlasma calcium concentrations were normalized to the mean plasma albumin concentration.bPlasma 1,25-dihydroxyvitamin D concentrations were measured in two male kl203X/203X mice, and the value for each individual mouse, which is provided in the table, is >5 SD above the mean of the male wild-type mice.cMale and female kl203X/203X mice had plasma FGF23 concentrations that were above the upper limit of assay detection, indicative of marked FGF23 elevations. ↑, increased; ALP, alkaline phosphatase activity; ALT, alanine aminotransferase; FGF23, fibroblast growth factor; 1,25(OH)2D, 1,25-dihydroxyvitamin D.*p**p***pPlasma analysis of ~5 week old kl203X mice.
