Overview of the ALLSorts classification architecture. In blue are the meta-subtypes that represent classes that have convergent or overlapping signals contained in their nested subtypes. Green nodes are terminal subtypes. Red nodes exist in the hierarchy, but classification currently terminates at the parent node because of a lack of training samples. CRLF2(non–Ph-like) is not included in this classification as its identification is better suited to alternate analysis. IGH-IL3 is also not included given only a single case was identified across all cohorts.
