Insights

Mucopolysaccharidoses (MPS) are serious hereditary diseases. Neurological complications significantly impact MPS severity, necessitating early diagnosis and intervention for affected children.

Area of Science:

  • Biochemistry
  • Genetics
  • Pediatrics

Context:

  • Mucopolysaccharidoses (MPS) are a group of rare, inherited metabolic disorders.
  • Neurological complications are a primary driver of disease severity in MPS.
  • A 12-year retrospective study was conducted at Sfax University Hospital's pediatric department.

Purpose:

  • To analyze the clinical presentation and characteristics of mucopolysaccharidosis cases.
  • To document the prevalence of different MPS subtypes within the studied cohort.
  • To evaluate the diagnostic and therapeutic approaches for MPS in a pediatric setting.

Summary:

  • The study identified 11 pediatric cases of MPS, including Hurler disease, Sanfilippo syndrome (types II A and III B), Morquio A, and Maroteaux Lamy.
  • Common clinical findings included growth delay (81.8%), craniofacial dysmorphism (100%), spinal deformities (63.6%), psychomotor regression (54.5%), hepatosplenomegaly (36.4%), and corneal opacities (45.4%).
  • Consanguinity was high (90%), with disease onset between 6 months and 4 years.

Impact:

  • This study highlights the significant clinical burden of MPS in children, particularly neurological and physical manifestations.
  • Findings underscore the importance of early diagnosis, genetic counseling, and antenatal diagnosis for managing MPS.
  • The limited therapeutic options emphasize the need for further research into effective treatments for these debilitating hereditary diseases.

Glycosaminoglycans01:23

Glycosaminoglycans

Glycosaminoglycans (GAGs), also known as mucopolysaccharides, are long and linear polymers comprising of specific repeating disaccharides - the amino sugar that can be N-acetylglucosamine or N-acetylgalactosamine, and a uronic acid that is usually glucuronic acid or iduronic acid.
GAGS are found in the extracellular matrix of vertebrates, invertebrates, and bacteria. Due to their polar nature they attract water, and serve as excellent lubricants or shock absorbers in an animal body.

Proteoglycans01:05

Proteoglycans

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,...
Lysosomal Hydrolases01:22

Lysosomal Hydrolases

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,...
