Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty eight tests were carried out on mutant mice and fourteen significant abnormalities were observed. Homozygous mutants were subviable and had decreased body weights, length of long bones and decreased circulating glucose levels, numerous abnormal body composition, X-ray imaging, eye morphology and haematology parameters; males also had a decreased grip strength, a short upturned snout, and abnormal indirect calorimetry and plasma chemistry parameters. Males (but not females) were also infertile. In addition, heterozygote mutants displayed premature hair follicle exogen.
