Serum contains several hexosaminidase forms. Two, HEX A and HEX B, migrate in both DEAE cellulose and isoelectric focussing systems like their tissue counterparts. A major group of serum hexosaminidases migrate in an intermediate position. These form

Diphenylhydantoin (DPH) may act by affecting ATPase activity. Using equilibrium dialysis we have found that DPH has a high affinity for subcellular fractions rich in ATPases. This affinity is decreased by Ca ++ . The Ca ++ effect is prevented by Mg +

In the past five years, rapid advances in the antenatal diagnosis of genetic disease have been made. In our center, an Amniotic Fluid Study Group has been formed for research in this area. In addition, an Antenatal Genetic Clinic with a multidiscipli

This report describes morphologic changes in a 19-week saline-aborted fetus with Tay-Sachs disease (TSD, GM 2 gangliosidosis) diagnosed in utero and subsequently confirmed by biochemical and morphological studies of fetal tissues. Typical membranous

Neonatal ascites is usually attributed to hematologic, genitourinary, gastrointestinal tract, or congenital heart disease. When these lesions have been excluded, metabolic storage disorders should be considered in the differential diagnosis. We repor

Concentrations of GL-la (glucocerebroside) (8.36 nmol/ml), GL-2a (lactosylceramide) (4.03 nmol/ml), GL-3a (globotriosylceramide) (2.25 nmol/ml) and GL-4a (globotetraosylceramide) (2.87 nmol/ml) have been determined in normal plasma and compared to co

Tay-Sachs disease results from a loss of activity of hexosaminidase A (HEX A) in body tissues and fluids. Heterozygotes for the disease are usually identified by their relatively low ratio of heat-labile HEX A to total hexosaminidase. During pregnanc

We examined eight published methods for the assay of glucocerebrosidase using the natural substrate glucocerebroside and tabulated the variable components and conditions while comparing these methods to ours. In each case assays were performed using
