Chromobox homolog 7 is a protein that in humans is encoded by the CBX7 gene.^[5] The loss of CBX7 gene expression has been shown to correlate with a malignant form of thyroid cancer.^[6]

Model organisms have been used in the study of CBX7 function. A conditional knockout mouse line, called Cbx7^{tm1a(KOMP)Wtsi}^[13]^[14] 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.^[15]^[16]^[17] Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.^[11]^[18] Twenty six tests were carried out and three significant phenotypes were reported. Homozygous mutant female adults showed a decreased response to stress-induced hyperthermia and had an increased red blood cell count. Animals of both sex had an integument phenotype when tail epidermis was examined.^[11]
