multiple sulfatase deficiency
mul·ti·ple sul·fa·tase de·fi·cien·cy
[MIM*272200]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.
