GM(1) gangliosidosis is a rare disorder characterized by deficiency of the ss-galactosidase enzyme, with the resulting accumulation of glycolipids, oligosaccharides and especially GM(1) ganglioside. It can be classified into three clinical types according to the time of onset: infantile, juvenile
The authors report a case of unsuspected fetal storage disorder initially diagnosed by placental examination performed because of a transient ascites at 28 weeks of gestation. At birth mild dysmorphic features and gradual neurological deterioration were observed. Highly elevated alkaline phosphatase
We report a new case of GM1-gangliosidosis diagnosed in a 5 months old baby who was admitted at birth to our Neonatology Unit because of congenital ascites. The antenatal diagnostic techniques, including ultrasound, maternal antibody screen and fetoscopy with fetal karyotyping, as well as postnatal
We performed a systematic review of the literature to evaluate the incidence and types of lysosomal storage disorders (LSDs) in case series of nonimmune hydrops (NIH). PubMed and Ovid were reviewed for case series evaluating the workup of NIH diagnosed in utero or in the neonatal period in human
Two cases of beta-glucuronidase deficiency (mucopolysaccharidosis VII), presented with fetal hydrops at 20 and 26 weeks of gestation. The enzyme deficiency was observed in cultured amniotic fluid cells and in fetal plasma from cord-blood and was confirmed after termination of pregnancy. A third case
A six-month-old female gypsy child, the daughter of second degree cousins, born after a full-term pregnancy and normal delivery, is described. There was generalized neonatal edema. Abnormalities included psychomotor retardation from birth and progressive appearance of facial dysmorphism, organ
The number of metabolic disorders associated with nonimmune hydrops fetalis is very small and includes only Gaucher disease, GM1 gangliosidosis type 1, Hurler syndrome, and mucolipidosis type I. We report another association of a nonimmune hydrops fetalis with Niemann-Pick disease as evident by
Diagnosis of GM1 gangliosidosis (OMIM 230500) is usually based on the presence of physical signs of storage such as coarse facial features, corneal clouding, cherry red macula, hepatosplenomegaly and skeletal dysostosis. More rarely it can present as nonimmune hydrops. We describe a male patient
OBJECTIVE
Hydrops fetalis is a life-threatening fetal condition, and 85% of all cases are classified as nonimmune hydrops fetalis (NIHF). Up to 15% of NIHF cases may be due to inborn errors of metabolism (IEM), but a large proportion of cases linked to metabolic disorders remains undiagnosed. This
Prenatal diagnosis is available for many lysosomal storage disorders (LSD) using chorionic villus samples or amniocytes. Such diagnoses can be problematical if sample transport and culture are required prior to analysis. The purpose of this study was to identify useful biochemical markers for the
BACKGROUND
The first step in the diagnosis of oligosaccharidoses is to evidence abnormal oligosaccharides excreted in urine, usually performed by the poorly sensitive but efficient thin layer chromatography (TLC) method. Developing a tandem mass spectrometry (MS/MS) technique could be of great
BACKGROUND
The biological diagnosis of sphingolipidoses currently relies on the measurement of specific enzymatic activities and/or genetic studies. Lysosphingolipids have recently emerged as potential biomarkers of sphingolipidoses and Niemann-Pick type C in plasma.
METHODS
We developed a sensitive
