Alleles and phenotypes

All alleles(7) : Targeted(4) Gene trapped(3)
 

Mice homozygous for disruptions in this gene die within one day of birth due to respiratory and suckling problems. They exhibit abnormal cholesterol homeostasis with reduced tissue cholesterol levels and total sterol levels, enlarged bladders and sometimes cleft palate.
