Chromosome 1 open reading frame 38 is a protein that in humans is encoded by the C1orf38 gene. The gene is also known as ICB-1 and THEMIS2 in humans, and the orthologue in mice is BC013712. C1orf38 has been associated with cancer susceptibility.
Model organisms have been used in the study of C1orf38 function. A conditional knockout mouse line, called BC013712tm1a(KOMP)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: chromosomal instability was detect by a micronucleus test.
