Term Description

This entity has two names: "nucleolar organizing region (NOR) 90" versus "human upstream binding factor (hUBF)". Both names are right, and the literature looking for the antibody in autoimmune patients almost uniformly includes both names and the historical context. NOR90 stuck because it was called that by the author of the original finding in autoimmune patients (Rodriguez-Sanchez, et al, 1987), but a few years later (1994), the antigen was found to be identical to already characterized hUBF. So we are stuck with the 2 names. hUBF is more technically specific, and at least one recent review calls it "anti-hUBF, formerly anti-NOR 90" (Journal of Dermatology 2010; 37: 42-53). So we will use that as its primary name.

Part Description

LP71704-8   Human upstream binding factor
Human upstream binding factor (hUBF) is a nucleolar protein that plays a key role in rRNA production. The protein regulates rDNA transcription and also promotes rRNA synthesis. DNA binding to hUBF has the potential to alter chromatin by inducing chromatin remodeling. PMID: 25965800 Autoantibodies to hUBF (anti-hUBF) are associated with various connective tissue diseases, including systemic sclerosis, Raynaud's disease, rheumatoid arthritis and systemic lupus erythematosus. Anti-hUBF antibodies have also been associated with some malignancies. Anti-hUBF and anti-nucleolus-organizing region (NOR) 90 antibodies were originally described as distinct entities but later were recognized as being the same.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
