Outcome Measures

Primary Outcomes (1)

  • Development of a new MS-based biomarker for the early and sensitive diagnosis of Sanfilippo Type A-B-C-D disease from plasma

    New methods, like mass-spectrometry give a good chance to characterize specific metabolic alterations in the blood of affected patients that allow diagnosing in the future the disease earlier, with a higher sensitivity and specificity.

    24 months

Secondary Outcomes (1)

  • Testing for clinical robustness, specificity and long-term stability of the biomarker

    36 months

Study Arms (1)

Observation

Patients with Sanfilippo Type A-B-C-D disease or high-grade suspicion for Sanfilippo Type A-B-C-D disease

Sampling MethodProbability Sample
Study Population

Patients with Sanfilippo Type A-B-C-D disease or high-grade suspicion for Sanfilippo Type A-B-C-D disease

You may qualify if:

  • Informed consent will be obtained from the patient or the parents before any study related procedures.
  • Patients of both genders older than 2 month
  • The patient has a diagnosis of Sanfilippo Type A-B-C-D disease or a high-grade suspicion for Sanfilippo Type A-B-C-D disease
  • Positive family anamnesis for Sanfilippo Type A-B-C-D disease
  • Dysostosis multiplex without identifiable cause
  • Splenomegaly without identifiable cause
  • Hepatomegaly without identifiable cause
  • Heparan sulfate excretion in urine
  • CNS involvement without identifiable cause

You may not qualify if:

  • No Informed consent from the patient or the parents before any study related procedures.
  • Patients of both gender younger than 2 month
  • No diagnosis of Sanfilippo Type A-B-C-D disease or no valid criteria for profound suspicion of Sanfilippo Type A-B-C-D disease

Biospecimen

Retention: SAMPLES WITH DNA

For the development of the new biomarkers using the technique of Mass-spectrometry 10 ml EDTA blood or a dry blood spot filter card are taken. To proof the correct Sanfilippo Type A-B-C-D diagnosis in those patients where up to the enrollment in the study no ge-netic testing has been done, sequencing of Sanfilippo Type A-B-C-D will be done. The analyses will be done at the: Centogene AG Am Strande 7 18055 Rostock Germany
