Summaries for CTC1 Gene

Entrez Gene Summary for CTC1 Gene

  • This gene encodes a component of the CST complex. This complex plays an essential role in protecting telomeres from degradation. This protein also forms a heterodimer with the CST complex subunit STN1 to form the enzyme alpha accessory factor. This enzyme regulates DNA replication. Mutations in this gene are the cause of cerebroretinal microangiopathy with calcifications and cysts. Alternate splicing results in both coding and non-coding variants.

GeneCards Summary for CTC1 Gene

CTC1 (CTS Telomere Maintenance Complex Component 1) is a Protein Coding gene. Diseases associated with CTC1 include cerebroretinal microangiopathy with calcifications and cysts and coats disease. GO annotations related to this gene include single-stranded DNA binding.

UniProtKB/Swiss-Prot for CTC1 Gene

  • Component of the CST complex, a complex that binds to single-stranded DNA and is required to protect telomeres from DNA degradation. The CST complex binds single-stranded DNA with high affinity in a sequence-independent manner, while isolated subunits bind DNA with low affinity by themselves. In addition to telomere protection, the CST complex has probably a more general role in DNA metabolism at non-telomeric sites.

  • Cerebroretinal microangiopathy with calcifications and cysts (CRMCC) [MIM:612199]: An autosomal recessive pleiomorphic disorder characterized primarily by intracranial calcifications, leukodystrophy, and brain cysts, resulting in spasticity, ataxia, dystonia, seizures, and cognitive decline. Patients also have retinal telangiectasia and exudates (Coats disease) as well as extraneurologic manifestations, including osteopenia with poor bone healing and a high risk of gastrointestinal bleeding and portal hypertension caused by vasculature ectasias in the stomach, small intestine, and liver. Some individuals also have hair, skin, and nail changes, as well as anemia and thrombocytopenia. {ECO:0000269 PubMed:22267198, ECO:0000269 PubMed:22387016}. Note=The disease is caused by mutations affecting the gene represented in this entry.
