1. A method of diagnosing or monitoring the status of systemic lupus erythematosus (SLE) in a subject or patient comprising:
- detecting the expression of all genes of a diagnostic set in the subject or patient wherein the diagnostic set comprises two or more genes having expression correlated with the classification or status of SLE; and
diagnosing or monitoring the status of SLE in the subject or patient by applying at least one statistical method to the expression of the genes of the diagnostic set.

Abstract
The invention presents a method of diagnosing or monitoring the status of systemic lupus erythematosus (SLE) in a subject or patient comprising detecting the expression of all genes of a diagnostic set in the subject or patient wherein the diagnostic set comprises two or more genes having expression correlated with the classification or status of SLE; and diagnosing or monitoring the status of SLE in the subject or patient by applying at least one statistical method to the expression of the genes of the diagnostic set.

13. A method of diagnosing or monitoring the status of systemic lupus erythematosus (SLE) in a subject or patient comprising:
-
detecting the expression of all genes of a diagnostic set in a subject or patient wherein the diagnostic set comprises at least one gene from each of at least two gene clusters selected from cluster 1, cluster 2, cluster 3, cluster 4, cluster 5, cluster 6, cluster 7, cluster 8, cluster 9, cluster 10, cluster 11;
cluster 12, cluster 13, cluster 14, and cluster 15 of Table 1; anddiagnosing or monitoring the status of SLE in the subject or patient based on expression of the genes in the diagnostic set.

27. A method of diagnosing a patient as having a longitudinally stable classification of SLE comprising:
-
detecting the expression of two or more genes whose expression correlates with the expression of the IFI27 from about 0.5 to about 1.0 and from about −
0.5 to about −
1.0 calculated using Pearson correlation; anddiagnosing the patient as having type I or type II SLE based analyzing the expression of the two or more genes using a statistical method.

36. A method of producing a probe set for diagnosing or monitoring SLE in a subject or patient comprising:
-
selecting at least one gene from each of at least two of the gene clusters of Table 1 and at least two genes from Table 2; and producing a probe set consisting of at least one oligonucleotide that detects the expression of each of the selected genes. - View Dependent Claims (37)

38. A method for predicting flare in a patient diagnosed with SLE comprising:
-
analyzing expression in a sample from the patient to produce a gene expression profile wherein a first portion of the analysis comprises using the expression of at least one gene selected from each of at least two of the clusters 1 through 15 of Table 1 and at least one statistical method to produce a patient gene expression profile, and a second portion of the analysis comprises using expression of at least two genes selected from Table 2 and a linear algorithm to classify the patient as having type 1 SLE or type 2 SLE; and predicting flare by comparing the patient gene expression profile at least one reference profile. - View Dependent Claims (39)
