SPORTAX Thomas Klockgether Sporadic ataxia Study natural history Develop biomarkers Explore genetic and immunological basis HCP
  1. Progressive ataxia
  2. Disease onset after the age of 40 years
  3. Informative and negative family history (no similar disorders in first- and second-degree relatives; parents older than 50 years, or, if not alive, age at death of more than 50 years, no consanguinity of parents)
  4. No established acquired cause of ataxia

Clinical: No onset of ataxia in association with stroke, encephalitis, sepsis, hyperthermia or heat stroke; no chronic diarrhea; no unexplained visual loss; no alcohol abuse; no chronic intake of anticonvulsant drugs; no other toxic causes; no malignancies; no rapid progression (development of severe ataxia in less than 12 weeks); no insulin-dependent diabetes mellitus

Imaging: No evidence of multiple sclerosis, ischemia, hemorrhage or tumor of the posterior fossa; absence of signal abnormalities on T2/FLAIR-images except abnormalities compatible with MSA

Laboratory: Negative molecular genetic testing for FRDA (only required if there is no cerebellar atrophy on MRI, SCA1, SCA2, SCA3, SCA6, FMR1 premutation (only required if prominent tremor, cognitive impairment or signal abnormality on T2/FLAIR images in the middle cerebellar peduncle); antineuronal antibodies negative (only required, if disease duration less than 3 years); normal levels of vitamin B12; VDRL negative; normal thyreoid function

EFACTS Jörg B. Schulz (Aachen) Friedreich's Ataxia

This is a multi-centre, multi-national, prospective, observational study of Friedreich's Ataxia (FRDA) with a control group to:

  • obtain natural history data on individuals affected by FRDA
  • relate clinical assessments and results from proteomic analyses
  • expedite identification and recruitment of participants for clinical trials
  • develop and validate sensitive and reliable outcome measures for detecting onset and change over the natural course of FRDA which may also be potential outcome measures for use in future clinical trials and clinical care
  • plan for future research studies

Inclusion Criteria:

  • Genetic diagnosis of FRDA
  • For control research participants: genetically confirmed absence of FRDA

Exclusion Criteria:

  • no signed informed consent form
  • no social security
  • already included in another clinical trial
  • deprived of their liberty
  • local anaesthesic contraindications (for biopsy)

HCP Inclusion:
Patients with ataxia onset <40 years, a sporadic or autosomal-recessive family history, without transmission in 2 generations; and no evidence for a secondary ataxia; a recessive ataxia mutation may already have been identified
