Silva O, Kurzer J. Nonleukemic T/B mixed phenotype acute leukemia with PHF6 and NOTCH1 mutations. Blood. 2021;138(9):818.

The author line “Oscar Silva and Jason Kurzer, Stanford University School of Medicine” should read “Oscar Silva, Stanford University School of Medicine; and Allison Shaw, Kaiser Permanente Regional Laboratory Northern California.” Blood Work publications are limited to 2 authors, and the original authors and the new author agreed that Allison Shaw should be listed as an author on the basis of the individuals’ relative contributions to the work.

In the first paragraph of the text, “Cytogenetics showed 46,XX, and fluorescence in situ hybridization was negative for BCR-ABL1 and MLL rearrangements” should read “Cytogenetics showed gain of 9q, but fluorescence in situ hybridization was negative for BCR-ABL1 and MLL rearrangements.”
