MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of a family of proteins that are components of the Crumbs cell polarity complex. In mammals, members of this family are thought to play a role in many cellular processes in early embryonic development. A similar protein in Drosophila determines apicobasal polarity in embryonic epithelial cells. Mutations in this gene are associated with focal segmental glomerulosclerosis 9, and with ventriculomegaly with cystic kidney disease. [provided by RefSeq, Aug 2016]
PHENOTYPE: Homozygous inactivation of this gene causes severe gastrulation defects, impaired somitogenesis and organogenesis. and complete embryonic death by E12.5. Several organ primordia, including neuroepithelium, gut, and heart, fail to form properly. [provided by MGI curators]
