About CTC1

Cytogenetic location: 17p13.1 Genomic coordinates (GRCh38): 17:8,224,815-8,248,056 (from NCBI)

This gene has 28 transcripts (splice variants), 181 orthologues and is associated with 4 phenotypes. Ubiquitous expression in lymph node (RPKM 10.4), spleen (RPKM 9.8) and 25 other tissues.

Summary

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.
