Chromodomain-helicase-DNA-binding protein 7 also known as ATP-dependent helicase CHD7 is an enzyme that in humans is encoded by the CHD7 gene.[1][2]

CHD7 is an ATP-dependent chromatin remodeler homologous to the Drosophila trithorax-group protein Kismet.[3] Mutations in CHD7 are associated with CHARGE syndrome.[4]

Model organisms

Model organisms have been used in the study of CHD7 function. A conditional knockout mouse line, called Chd7tm2a(EUCOMM)Wtsi[12][13] 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.[14][15][16]

Bergmeister's papilla, histological section.

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[10][17] Twenty four tests were carried out on mutant mice and five significant abnormalities were observed.[10] 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.[10]
