Model organisms
Model organisms have been used in the study of CHD7 function. A conditional knockout mouse line, called Chd7tm2a(EUCOMM)Wtsi 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 — at the Wellcome Trust Sanger Institute.



Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.

Twenty four tests were carried out on mutant mice and five significant abnormalities were observed. No homozygous mutant embryos were identified during gestation, and therefore none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice. Male heterozygotes displayed abnormal pelvic elevation in a modified SHIRPA test and have a high incidence of Bergmeister's papilla in both eyes. When the brains of heterozygous animals were studied, an absence of corpus callosum was observed.
