About DKC1

Cytogenetic location: Xq28 Genomic coordinates (GRCh38): X:154,762,864-154,777,689 (from NCBI)

This gene has 32 transcripts (splice variants), 216 orthologues and is associated with 5 phenotypes. Ubiquitous expression in bone marrow (RPKM 13.6), lymph node (RPKM 11.6) and 25 other tissues.

Summary

This gene functions in two distinct complexes. It plays an active role in Telomerase stabilization and maintenance, as well as recognition of snoRNAs containing H/ACA sequences which provides stability during biogenesis and assembly into H/ACA small nucleolar RNA ribonucleoproteins (snoRNPs). This gene is highly conserved and widely expressed, and may play additional roles in nucleo-cytoplasmic shuttling, DNA damage response, and cell adhesion. Mutations have been associated with X-linked dyskeratosis congenita. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
