Consistent with this expectation, throughout the study axi-cel was not detected in MDS/AML samples at meaningful levels in the myeloid compartment in scRNA (Figure S3C), and scDNA (Figure 6F), nor did CAPP-seq analysis of MDS/AML samples support the presence of CAR-positive malignant clones (Figure S7E). The gene discussed is CEL; the disease is myelodysplastic syndrome.
