[Mucopolysaccharidosis V (Ullrich-Scheie syndrome) (author's transl)]
Abstract:
Mucopolysaccharidosis V (Scheie's syndrome, MPS-IS) is a very rare, autosomal recessively inherited metabolic disease. The degradation of dermatan sulphate and heparan sulphate is disturbed due to alpha-L-iduronidase deficiency, leading to intracellular storage and excessive urinary secretion of these substances. The characteristic clinical features are contractures (claw-like flexion of the fingers), umbilical and inguinal herniae, corneal opacity, hepatomegaly, myocardiopathy and minor skeletal malformations. A patient with Scheie's syndrome is now reported for the first time in Austria; the results of the clinical, biochemical, chromosomal, dermatoglyphic and electron optical investigations are described and discussed.
Insights
Mucopolysaccharidosis V (Scheie's syndrome) is a rare metabolic disorder caused by alpha-L-iduronidase deficiency. This case report details the first Austrian patient, highlighting clinical and biochemical findings.
Area of Science:
- Biochemistry
- Genetics
- Metabolic Disorders
Background:
- Mucopolysaccharidosis V (Scheie's syndrome, MPS-IS) is an extremely rare autosomal recessive metabolic disease.
- It results from a deficiency in alpha-L-iduronidase, impairing dermatan and heparan sulfate degradation.
- This leads to intracellular accumulation and increased urinary excretion of these glycosaminoglycans.
Observation:
- The study reports the first case of Scheie's syndrome diagnosed in Austria.
- Clinical manifestations include contractures, hernias, corneal opacity, hepatomegaly, myocardiopathy, and skeletal abnormalities.
- Comprehensive investigations included clinical, biochemical, chromosomal, dermatoglyphic, and electron optical analyses.
Findings:
- The patient presented with characteristic clinical features of MPS-IS.
- Biochemical analyses confirmed alpha-L-iduronidase deficiency.
- Detailed investigations provided a thorough understanding of the disease presentation in this individual.
Implications:
- This case contributes to the understanding of Scheie's syndrome prevalence and presentation.
- It underscores the importance of early diagnosis and comprehensive evaluation for rare metabolic disorders.
- The findings aid in characterizing the clinical and biochemical spectrum of MPS-IS.
