Summary
This study identifies a rare phospholipidosis in a child, distinct from Niemann-Pick disease, characterized by phosphoglyceride accumulation. Diagnosis involves specific staining and hydrolysis tests for accurate identification of this rare genetic disorder.
Area of Science:
- Biochemistry
- Genetics
- Pediatric Pathology
Background:
- Phospholipidosis encompasses a group of rare genetic disorders characterized by the abnormal accumulation of phospholipids within cells.
- Distinguishing between different types of phospholipidosis is crucial for accurate diagnosis and management.
- Niemann-Pick disease is a well-known sphingomyelinosis, a subtype of phospholipidosis.
Observation:
- A 27-month-old girl presented with symptoms leading to a bioptic examination of appendix, skin, and liver specimens.
- Microscopic examination revealed an accumulation of phosphoglycerides exceeding that of sphingomyelin.
- This pattern differentiated the condition from Niemann-Pick disease and related sphingomyelinosis.
Findings:
- The diagnosed condition is a form of phospholipidosis, specifically characterized by excessive phosphoglyceride storage.
- This disorder aligns with previously described conditions like "kephalinosis" and cases reported by Wiedemann et al.
- The proposed term "Type II phospholipidosis" or "phosphoglyceridosis" accurately describes this specific disease entity.
Implications:
- The findings suggest a distinct classification within phospholipidosis, emphasizing phosphoglyceride accumulation.
- Iron hematoxylin staining is proposed as a diagnostic method, visualizing all phospholipids.
- Differential diagnosis can be aided by observing the effect of alkaline hydrolysis on staining, which differs between this condition and Niemann-Pick sphingomyelinosis.

01:02Phosphorylation
The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...

01:42Phosphoinositides and PIPs
Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...

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,...
01:28Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

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...
