Summaries for B9D1 Gene

Entrez Gene Summary for B9D1 Gene

  • This gene encodes a B9 domain-containing protein, one of several that are involved in ciliogenesis. Alterations in expression of this gene have been found in a family with Meckel syndrome. Meckel syndrome has been associated with at least six different genes. This gene is located within the Smith-Magenis syndrome region on chromosome 17. [provided by RefSeq, Mar 2016]

GeneCards Summary for B9D1 Gene

B9D1 (B9 Domain Containing 1) is a Protein Coding gene. Diseases associated with B9D1 include Joubert Syndrome 27 and Meckel Syndrome 9. Among its related pathways are Organelle biogenesis and maintenance and Regulation of PLK1 Activity at G2/M Transition. GO annotations related to this gene include hedgehog receptor activity. An important paralog of this gene is B9D2.

UniProtKB/Swiss-Prot for B9D1 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 ciliogenesis and sonic hedgehog/SHH signaling (By similarity).

  • Joubert syndrome 27 (JBTS27) [MIM:617120]: 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. JBTS27 inheritance is autosomal recessive. {ECO:0000269 PubMed:24886560}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Meckel syndrome 9 (MKS9) [MIM:614209]: 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:21493627}. Note=The disease is caused by mutations affecting the gene represented in this entry.
