Abs CD8 indicates absolute CD8 count; Tg, T-cell receptor gamma rearrangement; Spl, splenomegaly; Vβ, T-cell receptor variable β chain; Jβ, joining β chain of expanded clonal types; Addl dx, additional diagnoses; RCA, red cell aplasia; UC, ulcerative colitis; Pulm HTN, pulmonary hypertension; NA, not available; RA, rheumatoid arthritis.
There were 2 distinct clones for these patients; data in parentheses are for the second clone.
This patient had an additional minor clone (Vβ 13.1) detected as well.
