A retrospective analysis on magnetic resonance images from patients with mucopolysaccharidoses (MPS), including Sanfilippo syndrome, revealed jaw bone defects specific to certain disease subtypes. Researchers also found that some of these craniofacial abnormalities, which are those relating to the bones of the skull and face, were not corrected even…

Researchers have discovered a new mutation in the NAGLU gene that is associated with Sanfilippo syndrome type B. They described the mutation in a case report titled, “A novel mutation in the NAGLU gene associated with Sanfilippo syndrome type B (mucopolysaccharidosis III B),” published…
A new treatment approach effectively carried the enzyme defective in Sanfilippo type A syndrome into the brains of mice in a disease model, researchers report, suggesting the strategy used may be of future importance to patients. The study, “Reduction in Brain Heparan Sulfate with Systemic Administration of an IgG Trojan…
A new test that uses dried blood spots has been developed for diagnosing Sanfilippo syndrome type A. This test would prove especially useful for disease screening in newborns, according to a study. The study, “Detection of Mucopolysaccharidosis III-A (Sanfilippo Syndrome-A) in Dried Blood Spots (DBS) by Tandem Mass Spectrometry,” was published in …
Abeona Therapeutics has announced the opening of The Elisa Linton Center for Rare Disease Therapies, a commercial manufacturing facility for advanced gene and cell therapies in Cleveland, Ohio.

Levels of Specific Sugar May Be Potential Diagnostic Tool for Sanfilippo Syndrome, Other MPS Types
Using a specific technique to measure the levels of a sugar called glycosaminoglycan in blood and urine can identify all types of mucopolysaccharidosis (MPS) — including Sanfilippo syndrome — and help assess the therapeutic value of treatments, according to researchers. Their study, “Glycosaminoglycans analysis in blood and urine…
Sanfilippo syndrome patients present cardiac abnormalities with mild progression over time. However, these symptoms do not raise any specific concerns for gene transfer clinical trials in this patient population, according to a recent natural history study. The study, “Natural history of echocardiographic abnormalities in mucopolysaccharidosis III,” was…
Finding treatments and potential cures for rare diseases is crucial, but so is the quality of patients’ lives — a rather nebulous term that means different things to different people. “Recently, there’s been much more of a focus on Quality of Life (QoL) issues, real-world evidence and patient-reported outcomes,” said…
Sanfilippo syndrome type A patients treated with the gene therapy candidate ABO-102 continue to show robust and sustained clinical improvements in a Phase 1/2 trial, its developer, Abeona Therapeutics, reports. The company presented updated results of its open-label study (NCT02716246) at the recent American Society for…
