Trait: chronic lymphocytic leukemia

Experimental Factor Ontology (EFO) Information
Identifier EFO_0000095
Description B-cell chronic lymphocytic leukemia (B-CLL) is a type of B-cell non-Hodgkin lymphoma, and the most common form of leukemia in Western countries, affecting elderly adults (mean age of 67 and 72 years) with a slight male predominance (1.7:1), and characterized by a highly variable clinical presentation that can include asymptomatic disease or non-specific B-symptoms such as unintentional weight loss, severe fatigue, fever (without evidence of infection), and night sweats as well as cervical lymphadenopathy, splenomegaly and frequent infections. Some patients can also develop autoimmune complications such as autoimmune hemolytic anemia or immune thrombocytopenia. The clinical course is extremely heterogeneous with survival ranging from a few months to several decades. [Orphanet: 67038]

PSS001173 Cases were individuals with monoclonal B-cell lymphocytosis (MBL) from two Mayo Clincs.Within the Mayo Clinic Biobank, MBL was screened for using a highly sensitive, 8-color (CD38, CD45, Kappa, Lambda, CD19, CD23, CD5 and CD20) flow-cytometry assay with the capacity to detect clonal B-cell counts to the 0.005% level (1/20,000 events), and for each individual, 500,000 PBMC events were typically captured. Of the 560 MBL cases, 396 had low-count MBL (LC-MBL) and 164 had high-count MBL (HC-MBL). Wiithin the Mayo Clinic Biobank only a subset of participants had a complete blood count. therefore the percent of clonal B-cells out of total B-cells was used to categorize participants as LC- and HC-MBL. Based on prior evidence, those MBL individuals with a percent clonal B-cell <85% were defined as LC-MBL and those with percent clonal B-cells ≥85% as HC-MBL. Within the Mayo Clinic Chronic lymphocytic leukemia (CLL) Resource, MBL was classified by LC-MBL or HC-MBL according to the B-cell clone size of below or above 0.5 × 109/L threshold, respectively. —
