Type of disease: Rare conditions
Galactosialidosis is an autosomal recessive lysosomal storage disorder caused by mutations in the CTSA gene. It is characterized by coarse facial features, macular cherry-red spots, angiokeratoma (dark red spots on the skin), vertebral deformities, epilepsy, action myoclonus, and ataxia. There are three different types of galactosialidosis: early infantile, late infantile and juvenile/adult. The three forms of galactosialidosis are distinguished by the age at which symptoms develop and the pattern of features.
