MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that has been directly linked to Bardet-Biedl syndrome. The primary features of this syndrome include retinal dystrophy, obesity, polydactyly, renal abnormalities and learning disabilities. Experimentation in non-human eukaryotes suggests that this gene is expressed in ciliated cells and that it is involved in the formation of cilia. A mutation in this gene has also been implicated in nonsyndromic retinitis pigmentosa. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
PHENOTYPE: Mice homozygous for a null mutation display partial postnatal lethality with slow postnatal weight gain, age related obesity, impaired olfation, loss of cilia from the olfactory epithelium, impaired targeting of olfactory sensory neuron axons, retinal degeneration, and mild renal tubule dilation. [provided by MGI curators]
