FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a transmembrane protein, which is a component of the B9 complex involved in the formation of the diffusion barrier between the cilia and plasma membrane. Mutations in this gene cause Joubert syndrome (JBTS). Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2013]
PHENOTYPE: Mice homozygous for a gene trapped allele exhibit complete lethality throughout fetal growth and development, defective patterning of the ventral spinal cord, a striking loss in cilia, severe vascular defects, polydactyly, and microphthalmia. [provided by MGI curators]
