Summary
Hydrops fetalis, a severe fluid buildup in fetuses, can stem from rare metabolic disorders like galactosialidosis. Early prenatal diagnosis is crucial for managing future pregnancies.
Area of Science:
- Perinatology
- Medical Genetics
- Biochemistry
Background:
- Hydrops fetalis involves abnormal fetal fluid accumulation, detectable via prenatal ultrasound.
- It's classified as immune or non-immune, with non-immune causes including metabolic disorders.
Observation:
- Metabolic causes, particularly lysosomal storage disorders (LSDs), are increasingly identified as triggers for non-immune hydrops fetalis.
- Affected fetuses often exhibit severe symptoms like ascites, hepatosplenomegaly, and skeletal deformities.
Findings:
- This report details a case of galactosialidosis, a specific LSD, presenting as non-immune hydrops fetalis.
- Prenatal diagnosis of LSDs without a prior affected individual (index case) presents significant challenges.
Implications:
- Accurate diagnosis of LSDs causing hydrops fetalis is vital for reproductive planning and management of subsequent pregnancies.
- Understanding these metabolic links improves prenatal care and genetic counseling for affected families.

01:27Glucose Transporters
22.5K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:20Inborn Errors of Metabolism
142
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

01:05Proteoglycans
3.9K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

01:15Transcytosis of IgG
2.7K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

01:24Oligosaccharide Assembly
2.8K
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.

01:22Lysosomal Hydrolases
3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
