Morquio Syndrome Type A in Adulthood: A Rare Case Report with Multisystem Involvement

Abstract Introduction: Morquio syndrome type A (MPS IV) is an infrequent disorder of recessive autosomal pattern lysosomal storage disorder due to an inadequacy of N-acetylgalactosamine-6-sulfatase. It typically presents in early childhood with progressive skeletal dysplasia but may remain undiagnosed until adulthood in milder forms. Adult presentations are rare and often complicated by multisystem involvement.
