Abstract

Methods of diagnosing or monitoring an autoimmune or chronic inflammatory disease, particularly SLE in a patient by detecting the expression level of one or more genes or surrogates derived therefrom in the patient are described. Diagnostic oligonucleotides for diagnosing or monitoring chronic inflammatory disease, particularly SLE infection and kits or systems containing the same are also described.

Claims

1. A method of diagnosing or monitoring an autoimmune or chronic inflammatory disease in a patient, comprising detecting the expression level of a nucleic acid in said patient to diagnose or monitor said autoimmune or chronic inflammatory disease in said patient wherein said nucleic acid comprises the nucleotide sequence SEQ ID NO:

3305.

2. The method of claim 1 wherein said autoimmune or chronic inflammatory disease is systemic lupus erythematosis (SLE).

3. The method of claim 1 wherein said expression level is detected by measuring the RNA level expressed by said nucleic acid.

4. The method of claim 3, further comprising isolating RNA from said patient prior to detecting said RNA level expressed by said nucleic acid.

5. The method of claim 3 wherein said RNA level is detected by PCR.

6. The method of claim 3 wherein said RNA level is detected by hybridization.

7. The method of claim 3 wherein said RNA level is detected by hybridization to an oligonucleotide.

8. The method of claim 7 wherein said oligonucleotide comprises DNA, RNA, cDNA, PNA, genomic DNA, or synthetic oligonucleotides.
