Mucopolysaccharidosis Type IIIA (MPS IIIA), known as Sanfilippo syndrome type A, is a rare autosomal recessive lysosomal storage disorder caused by the mutations in the N-sulfoglucosamine Sulfohydrolase (SGSH) gene, encoding the enzyme heparan N-sulfatase (HNS). We obtained peripheral blood mononuclear cells (PBMCs) from a patient diagnosed with Sanfilippo syndrome carrying the mutation c.[706G>A(p.Asp235Asn)];c.[449G>A (p.Arg150Gln)] in the SGSH gene. We successfully generated an induced pluripotent stem cell (iPSC) line from isolated patient PBMCs using a non-integrative Sendai virus method. The hiPSCs displayed characteristics of embryonic stem cells, showed the ability to differentiate into three germ layers, and presented a normal karyotype.

Background: Mucopolysaccharidosis type III (MPS III) is a rare lysosomal storage disease with systemic complications. This scoping review aimed to synthesise evidence regarding methods to diagnose and monitor MPS III.
Methods: We searched 10 databases for English and Spanish citations published from 2017 to 2022.

Therapeutic options range from disease-specific, with varying levels of effectiveness, to purely supportive. This spectrum is illustrated by the three diseases Gaucher disease type 1 (effective disease-specific therapies), Fabry disease (disease-specific therapies with variable effectiveness), and mucopolysaccharidosis type III A/B (supportive care only).

Mucopolysaccharidoses (MPSs) are complex lysosomal diseases that result in the accumulation of glycosaminoglycans (GAGs) in urine, blood, and tissues. Lysosomal enzymes responsible for GAG degradation are defective in MPSs. GAGs including chondroitin sulfate (CS), dermatan sulfate (DS), heparan sulfate (HS), and keratan sulfate (KS) are biomarkers for MPSs.

Mucopolysaccharidosis II (MPS II; Hunter syndrome) is a rare, X-linked, recessive lysosomal storage disorder that impacts approximately 1:162000 live births. It is caused by deficiencies in the lysosomal enzyme iduronate-2-sulfatase (I2S), resulting in harmful accumulation of specific glycosaminoglycans in cells, tissues and organs throughout the body. Clinical manifestations are varied and include airway obstruction, impaired mobility and, in two-thirds of cases, neurocognitive impairment (neuronopathic MPS II).
