24-Dehydrocholesterol reductase
24-dehydrocholesterol reductase is a protein that in humans is encoded by the DHCR24 gene.[5][6]

Model organisms have been used in the study of DHCR24 function. A conditional knockout mouse line, called Dhcr24tm1a(EUCOMM)Wtsi[11][12] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[13][14][15]
Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[9][16] Twenty-six tests were carried out on mutant mice and two significant abnormalities were observed.[9] Few homozygous mutant embryos were identified during gestation, and none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice and no further abmornalities were observed.[9]
