SAMSN1 and myeloid leukemia: Other genes, including CD24 (a sialoglycoprotein expressed on mature granulocytes and B cells), PASD1 (a transcription factor expressed in diffuse large B-cell lymphoma), MS4A3 (a hematopoietic cell-specific membrane protein), SAMSN1 (a protein with an SH3 domain and nuclear localization signals) and MS4A4 (from the same family as MS4A3) are also interesting because of their involvement with tumors but their relationships to myeloid leukemia are not clear.
