| Disease ID | Source | Name | Description |
| 253200 | OMIM | Mucopolysaccharidosis 6 (MPS6) | An autosomal recessive lysosomal storage disease characterized by intracellular accumulation of dermatan sulfate. Clinical features can include abnormal growth, short stature, stiff joints, skeletal malformations, corneal clouding, hepatosplenomegaly, and cardiac abnormalities. A wide variation in clinical severity is observed. The disease is caused by variants affecting the gene represented in this entry. |
| 272200 | OMIM | Multiple sulfatase deficiency (MSD) | 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. The protein represented in this entry is involved in disease pathogenesis. Arylsulfatase B activity is impaired in multiple sulfatase deficiency due to mutations in SUMF1. SUMF1 mutations result in defective post-translational modification of ARSB at residue Cys-91 that is not converted to 3-oxoalanine. |
