| description | Testing for an elevated ratio of 25HDN to 24,25 DHD can be used to reveal the likely presence of mutations in the CYP24A1 gene. CYP24A1 converts 25 hydroxyvitamin D to 24,25 dihydroxyvitamin D, a process thought to prevent overproduction of the active metabolite 1,25 dihydroxyvitamin D. | |
