Summaries for TCTN2 Gene

Entrez Gene Summary for TCTN2 Gene

  • This gene encodes a type I membrane protein that belongs to the tectonic family. Studies in mice suggest that this protein may be involved in hedgehog signaling, and essential for ciliogenesis. Mutations in this gene are associated with Meckel syndrome type 8. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

GeneCards Summary for TCTN2 Gene

TCTN2 (Tectonic Family Member 2) is a Protein Coding gene. Diseases associated with TCTN2 include Meckel Syndrome, Type 8 and Joubert Syndrome 24. Among its related pathways are Organelle biogenesis and maintenance and Regulation of PLK1 Activity at G2/M Transition.

UniProtKB/Swiss-Prot for TCTN2 Gene

  • Component of the tectonic-like complex, a complex localized at the transition zone of primary cilia and acting as a barrier that prevents diffusion of transmembrane proteins between the cilia and plasma membranes. Required for hedgehog signaling transduction (By similarity).

  • Joubert syndrome 24 (JBTS24) [MIM:616654]: A form of Joubert syndrome, a disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy, renal disease, liver fibrosis, and polydactyly. {ECO:0000269 PubMed:21565611, ECO:0000269 PubMed:25118024}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Meckel syndrome 8 (MKS8) [MIM:613885]: A disorder characterized by a combination of renal cysts and variably associated features including developmental anomalies of the central nervous system (typically encephalocele), hepatic ductal dysplasia and cysts, and polydactyly. {ECO:0000269 PubMed:21462283}. Note=The disease is caused by mutations affecting the gene represented in this entry.
