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

Disorders for TCTN2 Gene

(1) OMIM Diseases for TCTN2 Gene (613846)


  • 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.
  • Note=Defects in TCTN2 may be a cause 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 and renal disease.
