What is the official name of the NOP10 gene?

The official name of this gene is “NOP10 ribonucleoprotein.”

NOP10 is the gene's official symbol. The NOP10 gene is also known by other names, listed below.

What is the normal function of the NOP10 gene?

From NCBI GeneThis link leads to a site outside Genetics Home Reference.:

This gene is a member of the H/ACA snoRNPs (small nucleolar ribonucleoproteins) gene family. snoRNPs are involved in various aspects of rRNA processing and modification and have been classified into two families: C/D and H/ACA. The H/ACA snoRNPs also include the DKC1, NOLA1 and NOLA2 proteins. These four H/ACA snoRNP proteins localize to the dense fibrillar components of nucleoli and to coiled (Cajal) bodies in the nucleus. Both 18S rRNA production and rRNA pseudouridylation are impaired if any one of the four proteins is depleted. The four H/ACA snoRNP proteins are also components of the telomerase complex. This gene encodes a protein related to Saccharomyces cerevisiae Nop10p. [provided by RefSeq, Jul 2008]

From UniProtThis link leads to a site outside Genetics Home Reference.:

Required for ribosome biogenesis and telomere maintenance. Part of the H/ACA small nucleolar ribonucleoprotein (H/ACA snoRNP) complex, which catalyzes pseudouridylation of rRNA. This involves the isomerization of uridine such that the ribose is subsequently attached to C5, instead of the normal N1. Each rRNA can contain up to 100 pseudouridine ("psi") residues, which may serve to stabilize the conformation of rRNAs. May also be required for correct processing or intranuclear trafficking of TERC, the RNA component of the telomerase reverse transcriptase (TERT) holoenzyme.

How are changes in the NOP10 gene related to health conditions?

Genetics Home Reference provides information about dyskeratosis congenita, which is associated with changes in the NOP10 gene.
UniProtThis link leads to a site outside Genetics Home Reference. provides the following information about the NOP10 gene's known or predicted involvement in human disease.

Dyskeratosis congenita, autosomal recessive, 1 (DKCB1): A rare multisystem disorder caused by defective telomere maintenance. It is characterized by progressive bone marrow failure, and the clinical triad of reticulated skin hyperpigmentation, nail dystrophy, and mucosal leukoplakia. Common but variable features include premature graying, aplastic anemia, low platelets, osteoporosis, pulmonary fibrosis, and liver fibrosis among others. Early mortality is often associated with bone marrow failure, infections, fatal pulmonary complications, or malignancy. The disease is caused by mutations affecting the gene represented in this entry.
