Abstract

Insights

Mucopolysaccharidoses (MPS) patients frequently experience cardiovascular issues like thickened heart walls and valve problems. Early detection via echocardiography and electrocardiography is crucial for managing these inherited metabolic diseases.

Area of Science:

  • Cardiology
  • Genetics
  • Metabolic Disorders

Background:

  • Mucopolysaccharidoses (MPS) are rare inherited metabolic diseases.
  • MPS can lead to significant damage in various organs, including the heart.

Purpose of the Study:

  • To evaluate cardiovascular involvement in Taiwanese patients with MPS.
  • To analyze cardiac manifestations based on MPS type and patient age.

Main Methods:

  • Retrospective review of medical records for 60 MPS patients (2000-2012).
  • Analysis of echocardiogram and electrocardiogram data.
  • Cardiac parameters assessed by MPS type and age.

Main Results:

  • Type II was the most frequent MPS type (43%).
  • Common cardiac findings included thickened interventricular septum (55%), asymmetric septal hypertrophy (42%), and mitral valve prolapse (33%).
  • Valvular issues and cardiac hypertrophy were more prevalent in MPS I, II, and VI and progressed with age.

Conclusions:

  • Anatomical cardiovascular changes are common in all MPS types, particularly MPS I, II, and VI.
  • Cardiovascular abnormalities progress with age.
  • Echocardiography and electrocardiography are valuable tools for early detection and long-term follow-up of MPS patients.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

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,...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

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,...

Glucose Transporters01:27

Glucose Transporters

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:

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

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...
