Vision problems may be earliest symptom of Sanfilippo C: Study

Light-sensing cells in the eyes become damaged and die in Sanfilippo syndrome type C before the onset of behavioral symptoms, a new study indicates. Issues related to vision “may be the first truly distinctive symptom” of Sanfilippo for these patients, which suggests “better disease awareness among ophthalmologists could play…

Enzyme replacement therapy found effective in Sanfilippo type A mice

The investigational, brain-penetrating enzyme replacement therapy DNL126 was found to correct neurological signs of Sanfilippo syndrome type A in a mouse model, according to its developer, Denali Therapeutics. Now, the biopharmaceutical company plans to seek U.S. Food and Drug Administration permission — via an investigational new drug application…

Metabolites in patients’ urine may be markers of disease, ERT response

Researchers identified 11 new candidate metabolite biomarkers in the urine of people with Sanfilippo syndrome, a study reported. Metabolomics, or examining global changes in metabolites in metabolic disorders such as Sanfilippo syndrome, may shed light on underlying disease mechanisms and provide a source of noninvasive biomarkers to support diagnosis,…

Iminosugars may help advance treatments for Sanfilippo: Cell study

Treatment with sugary molecules called iminosugars can reduce the toxic buildup of heparan sulfate in cellular models of Sanfilippo syndrome, a new study reports. The study, “N-Substituted l-Iminosugars for the Treatment of Sanfilippo Type B Syndrome,” was published in the Journal of Medicinal Chemistry. Sanfilippo syndrome is…

Resveratrol Prevents Toxic Buildup in Cells of Sanfilippo Mouse Model

Treatment with resveratrol, a plant-derived compound that activates a cell cleansing process called autophagy, reduced the toxic buildup of heparan sulfate and normalized behavior in a mouse model of Sanfilippo syndrome. “Resveratrol normalized urinary [heparan sulfate] levels and attenuated abnormal behaviors in [Sanfilippo B] model mice, supporting further studies…

Increased Disease Severity Found With Age in Sanfilippo Youth

Neurological, behavioral, and MRI examinations of a group of children and adolescents with Sanfilippo syndrome in Brazil showed increased disease severity with age that coincided with progressive brain involvement, according to a new study. Changes in all areas increased in prevalence as the children grew, the researchers noted in…
