MLD is a disease due to a lysosomal storage defect. It is characterized by intralysosomal storage of cerebroside-3-sulfate in neural and non-neural tissues, with a diffuse loss of myelin in the central nervous system. Progressive demyelination causes a variety of neurological symptoms, including gait disturbances, ataxias, optical atrophy, dementia, seizures, and spastic tetraparesis. Three forms of the disease can be distinguished according to the age at onset: late-infantile, juvenile and adult.<ref>PMID:1673291</ref> <ref>PMID:1678251</ref> <ref>PMID:1670590</ref> <ref>PMID:1353340</ref> <ref>PMID:8101038</ref> <ref>PMID:8101083</ref> <ref>PMID:8095918</ref> <ref>PMID:7902317</ref> <ref>PMID:7906588</ref> <ref>PMID:8104633</ref> <ref>PMID:7909527</ref> <ref>PMID:7825603</ref> <ref>PMID:7860068</ref> <ref>PMID:7581401</ref> <ref>PMID:8891236</ref> <ref>PMID:9272717</ref> <ref>PMID:9090526</ref> <ref>PMID:9490297</ref> <ref>PMID:9600244</ref> <ref>PMID:9452102</ref> <ref>PMID:9819708</ref> <ref>PMID:10220151</ref> <ref>PMID:10477432</ref> <ref>PMID:10533072</ref> <ref>PMID:10381328</ref> <ref>PMID:10751093</ref> <ref>PMID:11061266</ref> <ref>PMID:11020646</ref> <ref>PMID:11456299</ref> <ref>PMID:11941485</ref> <ref>PMID:12503099</ref> <ref>PMID:12788103</ref> <ref>PMID:14517960</ref> <ref>PMID:14680985</ref> <ref>PMID:15326627</ref> <ref>PMID:15026521</ref> <ref>PMID:15710861</ref> <ref>PMID:18693274</ref> <ref>PMID:19606494</ref> <ref>PMID:20339381</ref> <ref>PMID:21265945</ref> Arylsulfatase A activity is defective in multiple sulfatase deficiency (MSD) [MIM:[https://omim.org/entry/272200 272200]. A clinically and biochemically heterogeneous disorder caused by the simultaneous impairment of all sulfatases, due to defective post-translational modification and activation. It combines features of individual sulfatase deficiencies such as metachromatic leukodystrophy, mucopolysaccharidosis, chondrodysplasia punctata, hydrocephalus, ichthyosis, neurologic deterioration and developmental delay. Note=Arylsulfatase A activity is impaired in multiple sulfatase deficiency due to mutations in SUMF1. SUMF1 mutations result in defective post-translational modification of ARSA at residue Cys-69 that is not converted to 3-oxoalanine.<ref>PMID:7628016</ref> <ref>PMID:15146462</ref> |
