<qa>  What is the most important question that is asked about the correlations between the two types of dataA particularly interesting question is whether the parameters generated by lineage tree analysis of Ig gene sequences are correlated with clinical parameters describing the patients e.g. age, gender, the course of the disease e.g. age of onset, disease duration, symptom severity and histological characteristics. We expect that analysis of these two types of data bioinformatical and clinical will reveal quite a few correlations, and that based on these correlations we may be able to enhance the set of diagnostic and prognostic tools currently available to clinicians specializing in IBD.
