Atypical presentation of mucopolysaccharidosis type IVA
A 14 year old patient with short stature, type I diabetes, and cataracts was referred for evaluation of avascular necrosis of the femoral head. Radiography was suggestive of spondyloepiphyseal dysplasia with decreased bone mineral density for age. Targeted molecular and biochemical testing were normal in this patient. Whole exome sequencing was performed and showed compound heterozygosity for p...
متن کاملReview of clinical presentation and diagnosis of mucopolysaccharidosis IVA.
Mucopolysaccharidosis type IVA (MPS IVA) was described in 1929 by Luis Morquio from Uruguay and James Brailsford from England, and was later found as an autosomal recessive lysosomal storage disease. MPS IVA is caused by mutations in the gene encoding the enzyme, N-acetylgalactosamine-6-sulfate sulfatase (GALNS). Reduced GALNS activity results in impaired catabolism of two glycosaminoglycans (G...
متن کاملAtypical Presentation of Mucopolysaccharidosis. Morquio’s Syndrome (Type IV-B): A Morbid Entity
Mucopolysaccharidosis (MPS) are a group of metabolic disorders of the lysosomal storage disease family caused by the absence or malfunctioning of lysosomal enzymes, which blocks degradation of mucopolysaccharides and leads to abnormal accumulation of heparan sulfate, dermatan sulfate, and keratan sulfate. Morquio’s syndrome is a rare autosomal-recessive mucopolysaccharidosis. This syndrome is c...
متن کاملAtypical clinical presentation of mucopolysaccharidosis type II (Hunter syndrome): a case report
INTRODUCTION We present a very rare case of mucopolysaccharidosis with atypical presentation such as mild mental retardation, an acrocephalic head and no corneal clouding. The purpose of presenting this case is to highlight the distinctive manifestation of mucopolysaccharidosis type II (Hunter syndrome). CASE PRESENTATION A 10-year-old East Asian boy presented with abdominal distension of fiv...
متن کاملRole of elosulfase alfa in mucopolysaccharidosis IVA
Mucopolysaccharidosis type IVA (MPS IVA or Morquio A) is an autosomal recessive lysosomal storage disease which results in a striking skeletal phenotype, but does not negatively impact the intellect of the patient. MPS IVA has a phenotypic continuum that ranges from a severe and rapidly progressing form to a slowly progressive form. The clinical diagnosis is often made in the preschool years ba...
