E76.219
Morquio mucopolysaccharidoses, unspecified
Clinical Classification Guidelines
Inclusion Terms
- Morquio syndrome
- Mucopolysaccharidosis, type IV
Medical Intelligence & Overview
Morquio mucopolysaccharidoses, also known as Morquio syndrome or Mucopolysaccharidosis Type IV, is a rare genetic disorder characterized by the body's inability to properly break down specific complex sugars called glycosaminoglycans. This leads to abnormal storage of these substances in the body, affecting bones, tissues, and organs. The condition can cause a range of physical challenges, including growth delays and skeletal abnormalities, but intelligence is typically unaffected.
Causes & Symptoms
Clinical Causes: Inherited genetic mutation affecting the enzymes responsible for breaking down glycosaminoglycans Autosomal recessive inheritance pattern, meaning both parents must carry the mutated gene for a child to be affected
Key Symptoms: Short stature and disproportionate skeletal growth Spinal curvature, such as scoliosis Joint stiffness and limited mobility Barrel-shaped chest Dental abnormalities, including misaligned teeth Uneven growth of bones and shortened limbs Potential respiratory issues due to chest and airway deformities Normal intelligence and cognitive development
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a combination of clinical examination, medical history review, and laboratory tests. Enzyme activity assays can identify deficiencies in the specific enzymes involved, while genetic testing confirms mutations in relevant genes. Imaging studies may reveal skeletal abnormalities characteristic of the disorder.
Treatment Protocols: Surgical procedures to correct skeletal abnormalities and improve mobility Physical therapy to enhance joint function and muscle strength Regular monitoring of respiratory and cardiac health Supportive therapies such as occupational therapy and speech therapy as needed
