For infants with ALL, we found that MDN1 was the most variable ALL-associated gene (Figure 2a, column 1; Infants: ALL), but also noted frequent variation in TTN, RBMX and MLL3 from the AML candidate list (Figure 2b, columns 1,2,3; Infants: ALL). This evidence concerns the gene RBMX and acute myeloid leukemia.
