Free sialic acid storage disease

What is Free sialic acid storage disease?


Free sialic acid storage diseases (free SASDs) are rare inherited lysosomal storage diseases. There are three forms of free SASDs; an infantile form (ISSD), an intermediate severe form and a slowly progressive adult form (Salla disease). Salla disease was first identified in 1979 by Dr Aula, and later in 1982 Dr Tondeur identified the infantile form.
