Model organisms have been used in the study of RHOT1 function. A conditional knockout mouse line, called Rhot1^{tm1a(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.

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty six tests were carried out on mutant mice and one significant abnormality was observed: no homozygous mutants survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice and no further abnormalities were observed.
