The fructose 1,6-diphosphatase activities in peripheral lymphocytes from the parents of a patient with fructose 1,6-diphosphatase deficiency were lower than the mean value of normal controls, but the value of the mother overlapped lower values for normal controls. The fructose 1,6-diphosphatase activities in lymphocytes of normal adults and the parents increased progressively during in vitro culture, but no enzyme activity could be detected in the lymphocytes of the patient even after culture. None of the values for the parents overlapped those of normal controls on either day 5 or 10 of culture. Thus, it seems probable that heterozygotes for fructose 1,6-diphosphatase deficiency can be distinguished from normal individuals by measuring the fructose 1,6-diphosphatase activity in their cultured lymphocytes.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D008297 Male Males
D010835 Phytohemagglutinins Mucoproteins isolated from the kidney bean (Phaseolus vulgaris); some of them are mitogenic to lymphocytes, others agglutinate all or certain types of erythrocytes or lymphocytes. They are used mainly in the study of immune mechanisms and in cell culture.
