Summary
Hereditary hyperferritinemia cataract syndrome (HHCS) is a rare genetic disorder. Early diagnosis is crucial, especially when children present with high ferritin levels and a family history of cataracts.
Area of Science:
- Genetics
- Pediatrics
- Ophthalmology
Background:
- Hereditary hyperferritinemia cataract syndrome (HHCS) is a rare autosomal dominant disorder.
- It results from mutations in the ferritin light chain gene (FTL).
- HHCS is characterized by elevated serum ferritin levels without iron overload and bilateral cataracts.
Observation:
- A 6-year-old Italian boy presented with unexplained, persistently high serum ferritin levels.
- Diagnostic uncertainty persisted until family history revealed cataracts in five relatives.
- Genetic testing confirmed the A37C mutation, diagnosing HHCS.
Findings:
- The case highlights HHCS as a differential diagnosis for isolated hyperferritinemia in children.
- Family history is a critical clue for diagnosing rare genetic syndromes.
- Genetic confirmation is essential for accurate diagnosis.
Implications:
- Emphasizes the importance of considering rare genetic conditions in pediatric diagnostics.
- Highlights the need for thorough family history assessment in cases of unexplained hyperferritinemia.
- Suggests early screening for cataracts in families with a history of HHCS.

01:25Jaundice
Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
01:20Inborn 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...
01:22Lysosomal 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,...
01:28The Early Endosome: Endocytosis of Transferrin
Essential proteins such as insulin or low-density lipoprotein (LDL) and micronutrients such as iron enter a eukaryotic cell through receptor-mediated endocytosis. Subsequently, the early endosomes fuse with the vesicles containing such receptor-ligand complexes and play a vital role in sorting the incoming ligands and receptors. While the ligands are either degraded inside the vesicle or released into the cytosol, their receptors are returned to the plasma membrane for further rounds of...
01:22Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
