Entrez Gene Summary for LZTFL1 Gene

  • This gene encodes a ubiquitously expressed protein that localizes to the cytoplasm. This protein interacts with Bardet-Biedl Syndrome (BBS) proteins and, through its interaction with BBS protein complexes, regulates protein trafficking to the ciliary membrane. Nonsense mutations in this gene cause a form of Bardet-Biedl Syndrome; a ciliopathy characterized in part by polydactyly, obesity, cognitive impairment, hypogonadism, and kidney failure. This gene may also function as a tumor suppressor; possibly by interacting with E-cadherin and the actin cytoskeleton and thereby regulating the transition of epithelial cells to mesenchymal cells. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2013]

GeneCards Summary for LZTFL1 Gene

LZTFL1 (Leucine Zipper Transcription Factor Like 1) is a Protein Coding gene. Diseases associated with LZTFL1 include Bardet-Biedl Syndrome 17 and Bardet-Biedl Syndrome. Among its related pathways are Cargo trafficking to the periciliary membrane and Organelle biogenesis and maintenance. GO annotations related to this gene include identical protein binding and protein complex binding.

UniProtKB/Swiss-Prot for LZTFL1 Gene

  • Regulates ciliary localization of the BBSome complex. Together with the BBSome complex, controls SMO ciliary trafficking and contributes to the sonic hedgehog (SHH) pathway regulation. May play a role in neurite outgrowth. May have tumor suppressor function.

  • Bardet-Biedl syndrome 17 (BBS17) [MIM:615994]: A syndrome characterized by usually severe pigmentary retinopathy, early-onset obesity, polydactyly, hypogenitalism, renal malformation and mental retardation. Secondary features include diabetes mellitus, hypertension and congenital heart disease. Bardet-Biedl syndrome inheritance is autosomal recessive, but three mutated alleles (two at one locus, and a third at a second locus) may be required for clinical manifestation of some forms of the disease. {ECO:0000269 PubMed:22510444, ECO:0000269 PubMed:23692385}. Note=The disease is caused by mutations affecting the gene represented in this entry. Patients carrying LZTFL1 mutations manifest mesoaxial polydactyly, a clinical feature very uncommon for Bardet-Biedl syndrome (PubMed:22510444 and PubMed:23692385). Some patients manifest situs inversus (PubMed:22510444). {ECO:0000269 PubMed:22510444}.
