SIALIDOSIS Meaning and
Definition
-
Sialidosis is a rare genetic disorder characterized by the deficiency or dysfunction of the enzyme NEU1, which is responsible for breaking down complex sugar molecules known as sialic acids. Sialidosis is a part of a group of disorders called lysosomal storage disorders, as the dysfunction of NEU1 leads to an accumulation of sialic acids within the lysosomes of cells.
Individuals affected by sialidosis may experience a wide range of symptoms that can vary in severity, depending on the particular form of the disorder. Symptoms often include skeletal abnormalities, such as joint stiffness, short stature, and dysostosis multiplex (abnormal bone development). Neurological manifestations, such as progressive intellectual disability, seizures, and developmental regression, are also common. Additionally, sialidosis may cause organomegaly (enlargement of organs), cardiomyopathy, and ocular abnormalities, such as cherry-red spots in the retina.
Two types of sialidosis have been identified: Type I and Type II. Type I is typically less severe and its symptoms usually develop during childhood or adolescence. Type II is more severe and progressive, with symptoms appearing earlier, often during infancy. Both types are inherited in an autosomal recessive manner, meaning that an affected individual must inherit two copies of the faulty gene, one from each parent.
There is currently no cure for sialidosis, and treatment mainly focuses on managing the symptoms and providing supportive care. This may include physical and occupational therapy, medications to control seizures or manage pain, and regular monitoring of affected organs.

Etymology of SIALIDOSIS
The word "sialidosis" is derived from the combination of two components: "sialo-" and "-idosis".
1. "Sialo-" is derived from the Greek word "sialon", meaning "saliva". In medical terminology, it refers to something related to saliva or salivary glands.
2. "-idosis" is a suffix commonly used in medical terminology to denote a disorder or disease.
Therefore, "sialidosis" refers to a disorder or disease related to the salivary glands. Specifically, it is used to describe a rare genetic disorder known as sialidosis, which is caused by the deficiency of an enzyme called neuraminidase.
