Abstract The lysosomal storage disorders are a collection of progressive, multisystem disorders that frequently present in childhood. Their timely diagnosis is paramount as they are becoming increasingly treatable. Musculoskeletal manifestations often occur early in the disease course, hence are useful as diagnostics clues The lysosomal storage diseases (LSDs) are a group of inherited metabolic disorders that are caused for the most part by enzyme deficiencies within the lysosome resulting in accumulation of undegraded substrate. This storage process leads to a broad spectrum of clinical manifestations depending on the specific substrate and site of accumulation

Lysosomal storage diseases (LSDs) are a class of metabolic disorders caused by mutations in proteins critical for lysosomal function. Such proteins include lysosomal enzymes, lysosomal integral membrane proteins, and proteins involved in the post-translational modification and trafficking of lysosomal proteins. There are many recognized forms of LSDs and, although individually rare, their. Lysosomal storage diseases (LSDs) include approximately 70 distinct disorders that collectively account for 14% of all inherited metabolic diseases. LSDs are caused by mutations in various enzymes/proteins that disrupt lysosomal function, which impairs macromolecule degradation following endosome-lysosome and phagosome-lysosome fusion and autophagy, ultimately disrupting cellular homeostasis Lysosomal storage diseases are inherited metabolic diseases that are characterized by an abnormal build-up of various toxic materials in the body's cells as a result of enzyme deficiencies.

Lysosomal Storage Diseases (LSDs) are caused by an accumulation of certain substances (called substrates) in a part of the cell called the lysosome. Lysosomes use proteins called enzymes to help break down or recycle many different substrates in the human body. If one of these enzymes does not work properly or is missing altogether, substrate.
The emergence of novel laboratory methods has facilitated the search for biomarkers in lysosomal storage diseases (LSDs), by allowing the systematic identification of molecules whose expression is altered as a result of the primary storage pathology. In Gaucher disease, for example, a chemokine, CCL18, has been identified as a biomarker for. Glycogen storage diseases (GSDs) are inherited inborn errors of metabolism of carbohydrates.
