Lysosomal Free Sialic Acid Storage Disorders

It is possible that the main title of the report Lysosomal Free Sialic Acid Storage Disorders is not the name you expected.
Free sialic acid storage disorders are a group of related disorders characterized by the abnormal accumulation of sialic acid in various cells and tissues of the body. These disorders are generally broken down into three subtypes: infantile free sialic acid storage disease (ISSD), the most severe form; Salla disease, the mildest form; and intermediate Salla disease which is less severe than ISSD, but more serious than Salla disease. The specific symptoms associated with these disorders can vary greatly. All the disorders are characterized by some degree of degeneration of nerve cells (neurodegeneration) and cognitive impairment. Free sialic acid storage disorders occur because of mutations of the SLC17A5 gene and are inherited in an autosomal recessive fashion.
Free sialic acid storage disorders belong to a larger group of diseases known as lysosomal storage disorders. Lysosomes are membrane-bound compartments within cells. They contain enzymes that break down large molecules such as proteins, carbohydrates and fats into their building blocks. Low levels or inactivity of a transport protein known as sialin leads to the abnormal accumulation (storage) of free sialic acid in the tissues of affected individuals. Sialin normally helps transport sialic acid out of lysosomes.
