Insights

L-2-Hydroxyglutaric aciduria (LHGA), a rare neurodegenerative disorder, co-occurred with medulloblastoma in a young child. This case highlights challenges in diagnosing and treating brain tumors in neurologically impaired pediatric patients.

Area of Science:

  • Biochemistry
  • Pediatric Neurology
  • Oncology

Background:

  • L-2-Hydroxyglutaric aciduria (LHGA) is a rare, autosomal recessive neurodegenerative disorder presenting in infancy with psychomotor retardation and ataxia.
  • Medulloblastomas are common pediatric solid tumors, frequently occurring in infancy and childhood.

Observation:

  • A 3-year-old boy with diagnosed LHGA developed a medulloblastoma.
  • This represents the first reported case of medulloblastoma coexisting with LHGA.

Findings:

  • The coexistence of central nervous system tumors with other metabolic neurodegenerative disorders is noted.
  • The study focuses on the diagnostic and therapeutic complexities of intracranial tumors in children with pre-existing neurological impairment from metabolic disorders.

Implications:

  • This case underscores the importance of considering oncological comorbidities in rare metabolic neurodegenerative diseases.
  • It highlights the diagnostic and therapeutic challenges in managing complex pediatric cases with combined neurological and oncological conditions.

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...
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:

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
