RESUMEN
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.

A partial long arm deletion of one X chromosome was observed in a patient with secondary amenorrhea and with no features of Turner's syndrome. It was shown that the deleted X chromosome was the inactivated one in all metaphases of the lymphocyte culture and of the tissue culture from gonadal biopsy. The patient was detected during a cytogenetic study of secondary amenorrhea of ovarian origin.
