1. A method for determining one or more correlating clonotypes of a disease unique to a subject comprising:
- (a) generating one or more clonotype profiles from at least two samples, wherein at least one sample is related to a first state of the disease, and(b) determining one or more correlating clonotypes unique to the subject based on comparing a clonotype profile of the at least one sample with one or more clonotype profiles of at least one other sample;
wherein each of said clonotype profiles is generated by the following steps;
(ii) spatially isolating individual molecules of recombined DNA sequences from T cells and/or B cells from the subject on a solid substrate;
(iii) amplifying molecules of the recombined DNA sequences on the solid substrate to form clusters;
(iv) sequencing by synthesis using reversibly terminated labeled nucleotides said recombined DNA sequences of the clusters to provide at least 1000 sequence reads each having an error rate;
(v) coalescing sequence reads of different clusters into different clonotypes of the recombined DNA sequences of the sample whenever the sequence reads are distinct with a confidence of at least 99.9 percent based on the error rate; and
(vi) determining a level of each of the different clonotypes of the recombined DNA sequences from said sample to generate said clonotype profile.

Abstract
There is a need for improved methods for determining the diagnosis and prognosis of patients with conditions, including autoimmune disease and cancer. Provided herein are methods for using DNA sequencing to identify personalized biomarkers in patients with autoimmune disease and other conditions. Identified biomarkers can be used to determine the disease state for a subject with an autoimmune disease or other condition.
