Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[13][20] Twenty three tests were carried out on mutant mice and six significant abnormalities were observed.[13]Hemizygous males were infertile and thus it was not possible to produce homozygous mutant female mice. The remaining tests were therefore carried out on heterozygous mutant females and hemizygous males. Both displayed decreased grip strength while the males also had decreased body weight, length, bone mineral content and atypical peripheral blood lymphocyte counts.[13]
