Clinical Findings and Natural History in Ten Unrelated Families with Juvenile and Adult GM1 Gangliosidosis.

ABSTRACT: We describe 12 subjects of ten unrelated families from the region of Campinas and the southern state of Minas Gerais, Brazil, who presented with juvenile (n = 4) and adult (n = 8) GM1 gangliosidosis.

Over time, all exhibited a combination of osteoarticular and neurologic degeneration with varying degrees of severity. Corneal clouding, angiokeratomas, and inguinal hernia were seen in one individual each. Other features commonly described in lysosomal storage disorders were not found in this series, such as coarse faces, gingival hypertrophy, visceromegaly, and cherry red spot. All subj
