multiple sulfatase deficiency

mul·ti·ple sul·fa·tase de·fi·cien·cy

[MIM*272200]
an inherited disorder (autosomal recessive) in which there is a failure to hydrolyze sulfatides and sulfated mucopolysaccharides; this failure leads to their accumulation in neural and extraneural tissues, causing disorders such as demyelination and facial and skeletal dysmorphism.

multiple sulfatase deficiency

A clinically and biochemically heterogeneous autosomal recessive disorder (OMIM:272200) caused by the simultaneous impairment of all sulfatases, due to defective post-translational modification and activation.

Clinical findings
Combined features of individual sulfatase deficiencies, such as metachromatic leukodystrophy, mucopolysaccharidosis, chondrodysplasia punctata, hydrocephalus, ichthyosis, neurologic deterioration and developmental delay.

Molecular pathology
Arylsulfatase A activity is impaired in multiple sulfatase deficiency due to mutations in SUMF1, which result in defective post-translational modification of ARSA at residue Cys-69 that is not converted to 3-oxoalanin.

The analysis of these proteins from blood spots allowed the detection of all patients with the following disorders: MPS I ([alpha]-t-iduronidase), MPS II (iduronate-2-sulfatase), MPS IIIA (sulfamidase), MPS VI (4-sulfatase), metachromatic leukodystrophy (arylsulfatase A), Niemann-Pick disease types A and B (acid sphingomyelinase), and multiple sulfatase deficiency. It also allowed the detection of most Fabry (agalactosidase), Pompe ([beta]-glucosidase), and Gaucher disease ([beta]-glucocerebrosidase) patients, as well as patients with I-cell disease.
