Genetic analysis has revealed a further class of subtypes, the so-called mosaic-types.
Systematic studies characterize the substitution process and substitution rate process of several classes of viral subtypes in, for example, Dengue, influenza subtype A, human immunodeficiency virus (HIV) and the virus responsible for sudden acute respiratory syndrome (SARS).
The different classes of molecular subtypes predict patient prognosis 22, 23 and aid in prediction of response to neoadjuvant treatment in node-negative patients 25.
Molecular profiling has revealed that breast cancer is not a single disease entity, but rather a class of heterogeneous subtypes, each with its own inherent biology and natural history.
All monocots only contain class XI myosins of subtypes 11A, 11C, 11E, 11G and 11H while eudicots also contain myosins of subtype 11B, 11D and 11F.
It is also crucial to enable separation of various classes or subtypes of the exosomes, based on their surface protein signature or other parameters.
The present study uniquely allows us to examine disease heterogeneity using biological and radiological data both individually, as well as collectively, to define homogeneous classes of patients or subtypes.
Both subtypes 6.1 and 6.3 could potentially be treated with all three classes of drugs, but subtype 6.2 is not expected to respond to PI3K inhibitors.
In particular, the proportions of the target class for subtypes BCR-ABL, E2A-PBX1, Mand and T-ALL are 0.04, 0.09, 0.06 and 0.15, respectively.
Second, although inclusion of TIS and drug-class treatment as a dummy variable did not significantly change the results, we were not able to take into account all the details of all the different classes and subtypes of drugs assumed by the patients, which in turn might have affected the results obtained.
