Genetics and pathology
- These are lysosomal storage disorders
- They are caused by mutations in the SLC17A5 gene on chromosome 6
- The transmission is autosomal recessive
- The gene encodes sialin
- The mutations impair sialic acid metabolism
- This results in sialic acid accumulation in tissue lysosomes
Types
Salla disease: clinical features
Infantile free sialic acid storage disease (ISSD): clinical features
Cerebellar ataxia with free sialic acid (CAFSA): clinical features
Magnetic resonance imaging (MRI) brain: features
Other investigations
