Comparison of serum parameters. Blood samples were collected from carotid artery (day 1 and 6) or heart (day 10 and thereafter) under conditions of anesthesia. Because sufficient amounts of blood could not be obtained from mice aged younger than 10 days, sera were pooled in each genotype for measurement of 1,25(OH)₂D. Other results represent mean ± SEM. The numbers of mice killed at each age were variable (average; WT n = 5, heterozygotes n = 9, and homozygotes n = 6). Statistical analysis was carried out by Dunnett’s method for comparison of multiple means (*P < 0.05; **P < 0.01). ND, not detected.
