The beta galactosidase activity of the above groups was comparable (p = 0.462, p = 0.507); however, there was a lower activity of beta galactosidase in the group of hematological tumors other than myeloma when compared to the group of healthy people (p = 0.129) (Figure 3B). The gene discussed is GLB1; the disease is hematopoietic and lymphoid system neoplasm.
