Optimal assay conditions are described for plasma alpha-galactosidase, beta-glactosidase, beta-glucuronidase, alpha-mannosidase, alpha-glucosidase, N-acetyl-beta-glucosaminidase, alpha-fucosidase, N-acetyl-alpha-glucosaminidase, acid phosphatase and arylsulphatase A. The levels of these activities in normal adults and children, and the stabilities of the activities on storage at -20 degrees C or 4 degrees C, are reported. The levels of these enzymic activities in plasma from patients with
Fabry
, Pompe, Sanfilippo A, Sanfilippo B, Tay Sachs and Hunter diseases, GM1-gangliosidosis and metachromatic leucodystrophy are described, and the possibility of using plasma hydrolase activities in the diagnosis of these conditions is discussed.

The possibility of lowering the level of ceramide-3 (galactosyl-alpha(1 leads to 4)-galactosyl-beta(1 leads to 4)-glucosyl-beta(1 leads to 1)-ceramide) in the plasma of patients with
Fabry's disease
was investigated. An immobilized alpha-galactosidase (alpha-D-galactoside galactohydrolase, EC 3.2.1.22) was prepared by coupling purified fig alpha-galactosidase to Sepharose 4B. The pH optimum for the hydrolysis of the artificial substrate p-nitro-phenyl-alpha-D-galactopyranoside was shifted by approx. 0.5--1.0 pH unit to higher pH values upon coupling of the enzyme to Sepharose 4B. The immobilized enzyme was more stable than the native enzyme to incubation at 60 degrees C. The immobilized enzyme was able to hydrolyse ceramide-3 either at pH 4.5 or at pH 7.4 in an artificial system in which sodium taurocholate was used to solubilize the substrate. In contrast, when the immobilized enzyme was incubated with normal plasma or plasma from a patient with
Fabry's disease
, in which elevated levels of ceramide-3 occur, no hydrolysis of the glycosphingo-lipid could be detected. The results suggest that lowering of level of ceramide-3 in plasma from patients with
Fabry's disease
by enzymic means is not feasible.

A preliminary report on the use of microtechniques for the detection of three lysosomal storage diseases (Tay-Sachs, GM1-gangliosidosis and
Fabry disease
) is presented. This microassay method uses from 100 to 300 cultured amniotic fluid cells or skin fibroblasts. A comparison between values for total activity and heat inactivated forms of hexosaminidase (in Tay-Sachs disease) is presented. The feasibility of the use of this microtechnique in prenatal diagnosis is discussed.

A family is described in which a 33-year-old man has classic X-linked recessive
Fabry disease
. His 2 sisters were discovered to be heterozygous carriers of the
Fabry
gene and to have both episodic and permanent neurological deficits including vertigo, tinnitus, long tract motor signs, and bladder incontinence. The most concise explanation for these findings is that the sisters manifest central nervous system complications of the
Fabry
carrier state. This family provides additional evidence that female carriers of rare X-linked recessive disorders may exhibit serious consequences of the disease, presumably related to tissue variability in expression of mutant enzyme activity.

Eighteen males, 17 of whom were members of a single family, affected with
angiokeratoma corporis diffusum
were examined in detail to determine the extent of clinical variation of the expression of what was almost certainly the same X-linked mutation in each. The commonest symptom was episodic bouts of severe, painful dysaesthesia in hands and feet. This was a major complaint of 12, a minor complaint of 5, and absent in 1. In over half the subjects, the skin rash that is considered a characteristic sign of the disease was absent or inconspicuous. All exhibited mild clubbing of fingers and toes, and 15 showed variable limitation of active and passive extension of the 5th fingers bilaterally. Only 2 (age 36 and 47) had evidence of significant renal disease. Electrocardiograms showed abnormally short PR intervals in 4, and right ventricular conduction disturbances in 5. Echocardiograms on 9 showed no evidence of myocardial dysfunction. The marked variation of the expression of some features of the disease indicates that the clinical expression of the mutation is likely to be subject to considerable genetic or environmental modification in each individual.

Fabry's disease
was originally considered a skin disease. Mainly affected are epidermis, kidney, heart and vessels. Newer studies show that the disease is an inherited defect of metabolism with abnormal accumulation of "Zeramid-Tri- or-Dihexoside" in different organs. The main clinical symptoms are epidermal changes, cornea verticillata and kidney changes. The diagnosis is verified by kidney biopsy or biochemical analysis of blood and urine. The activity of alpha-galactosidase in the blood is reduced, the secretion of Zeramid-Trihexoside in urine is increased. Causal therapy still does not exist, different methodes of treatment are discussed but still in the experimental stage. A case report is given.

A family in the north-east of England with Anderson--
Fabry's disease
is presented. Alpha-galactosidase activity in plasma and white cells was significantly reduced in three adult male members of the family. One of them had an abnormal chromosome karyotype pattern with an extra Y chromosome (47,XYY) and he was clinically less severely affected than his brothers. Coincidentally five other members of the family suffered from a form of familial spastic paraplegia.

Familial Dysautonomia (FD) is an autosomal recessive disease of unknown etiology, occurring primarily in Ashkenazi Jews. Patients are neurologically impaired, with deficits primarily in autonomic and sensory functions. The biochemical and genetic defects have remained elusive, precluding carrier detection and prenatal diagnosis. High-performance liquid chromatography data indicated up to a threefold increase in the neutral glycosphingolipid globotriaosylceramide in Dysautonomic fibroblasts and lymphoblasts. Total ganglioside values, measured by colorimetric, fluorometric or specific sodium borohydride incorporation, were decreased. Affected fibroblasts exhibited a range of pleomorphic phenotypes, such that the usual swirl-like confluent growth pattern of normal fibroblasts was distorted to varying degrees, suggesting abnormalities in the FD plasma membrane, possibly affecting cell-cell contacts. The glycosphingolipid increase could not be accounted for on the basis of markedly decreased alpha-galactosidase activity, as in
Fabry's disease
, where patients also display decreased autonomic function.

We used a high-performance liquid chromatography method to measure CSF gangliosides, neutral glycolipids, and sulfatides in patients with lysosomal storage disorders. These measurements could be done on less than 1 milliliter of CSF. In patients with GM1 gangliosidosis, GM1 ganglioside was increased, and in GM2 gangliosidosis patients, GM2 ganglioside was increased in CSF. Sulfatides were variably increased in CSF early in the course of the disease and appeared to be a means of monitoring patients, following bone marrow transplantation.
Fabry's disease
patients showed an increase in globotriaosylceramide, but Krabbe's disease patients did not demonstrate an increase in galactosylceramide. This study suggests that CSF glycosphingolipid measurements may prove helpful in the diagnosis and monitoring of lysosomal storage diseases.
