CBLN1 and rickets: The data obtained from this study showed that Cer(d18:1/16:0) and Cer(d18:1/18:0) were negatively related with 25(OH)D, whereas AMI patients with adequate 25(OH)D levels (≥30 ng/mL) showed reduced values of Cer(d18:1/16:0) and Cer(d18:1/18:0), which were particularly high in patients with severe hypovitaminosis D (<10 ng/mL).
