What are the signs and symptoms of galactosialidosis?

The early infantile form of galactosialidosis is associated with hydrops fetalis, inguinal hernia, and hepatosplenomegaly. Additional features include abnormal bone development (dysostosis multiplex) and distinctive facial features that are often described as 'coarse.' Some infants have an enlarged heart; an eye abnormality called a cherry-red spot (identified through an eye examination); and kidney disease that can progress to kidney failure. Infants with this form are usually diagnosed between birth and 3 months of age.[1]

The late infantile form of galactosialidosis shares some features with the early infantile form, although the signs and symptoms are somewhat less severe and begin later in infancy. This form is characterized by short stature, dysostosis multiplex, heart valve problems, hepatosplenomegaly, and 'coarse' facial features. Other symptoms seen in some individuals with this type include intellectual disability, hearing loss, and a cherry-red spot. Children with this condition typically develop symptoms within the first year of life.[1]

The juvenile/adult form of galactosialidosis has signs and symptoms that are somewhat different than those of the other two types. This form is distinguished by difficulty coordinating movements (ataxia), muscle twitches (myoclonus), seizures, and progressive intellectual disability. People with this form typically also have dark red spots on the skin (angiokeratomas), abnormalities in the bones of the spine, 'coarse' facial features, a cherry-red spot, vision loss, and hearing loss. The age at which symptoms begin to develop varies widely among affected individuals, but the average age is 16.[1]
