Summaries for TTC7A Gene

Entrez Gene Summary for TTC7A Gene

  • This gene encodes a protein containing tetratricopeptide repeats. Mutations in this gene disrupt intestinal development and can cause early onset inflammatory bowel disease and intestinal atresia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

GeneCards Summary for TTC7A Gene

TTC7A (Tetratricopeptide Repeat Domain 7A) is a Protein Coding gene. Diseases associated with TTC7A include Gastrointestinal Defects And Immunodeficiency Syndrome and Intestinal Atresia. An important paralog of this gene is TTC7B.

UniProtKB/Swiss-Prot for TTC7A Gene

  • Component of a complex required to localize phosphatidylinositol 4-kinase (PI4K) to the plasma membrane (PubMed:23229899, PubMed:24417819). The complex acts as a regulator of phosphatidylinositol 4-phosphate (PtdIns(4)P) synthesis (Probable). In the complex, plays a central role in bridging PI4KA to EFR3B and FAM126A, via direct interactions (By similarity).

  • Gastrointestinal defects and immunodeficiency syndrome (GIDID) [MIM:243150]: A rare, severe congenital disorder in which obstructions occur at various levels throughout the small and large intestines, ultimately leading to organ failure. Surgical interventions are palliative but do not provide long-term survival. Severe immunodeficiency may be associated with the phenotype. {ECO:0000269 PubMed:23423984, ECO:0000269 PubMed:23830146, ECO:0000269 PubMed:24292712, ECO:0000269 PubMed:24417819, ECO:0000269 PubMed:24931897, ECO:0000269 PubMed:25534311, ECO:0000269 PubMed:25546680, ECO:0000269 PubMed:25745186}. Note=The disease is caused by mutations affecting the gene represented in this entry. Phenotypic variations have been observed: the mildest case show intestinal aberrations consisting of bloody diarrhea, apoptotic enterocolitis, and acute graft-versus-host disease- (GVHD)-like symptoms, but no atresias (PubMed:25546680). Other patients show multiple intestinal atresias, some being associated with immunodeficiency syndrome, while other do not show immunodeficiency defects (PubMed:23423984). {ECO:0000269 PubMed:23423984, ECO:0000269 PubMed:25546680}.
