Brief Summary

RNALS is a multicentre, transversal, diagnostic and non-interventional study carried out in ALS reference centers; in order to identify a diagnostic signature for Amyotrophic Lateral Sclerosis by analyzing of coding and non-coding RNA contained in patients saliva. The study population consists of patients with definite or probable amyotrophic lateral sclerosis (ALS) according to the El Escorial criteria ("ALS Subjects" group) and subjects with no neurological history (Control group). The control group will be made up of caregivers of patients with ALS, and caregivers of patients with a pathology other than ALS. The ALS patients concerned by the study already benefit from routine medical care in ALS expert centers in France. The patients concerned by the study will be managed without modification of the care pathway, nor modification of the therapeutic indications, nor modification of the diagnostic or follow-up examinations necessary according to the context, which are carried out according to the recommendations of the HAS, CNGOF.

Study Population

The study population will be made up with amyotrophic lateral sclerosis (ALS) patients defined or probable according to El Escorial criteria ("ALS patients" group) and patients with no medical history or neurological symptoms (Control Group). The control group will be made up of people accompanying the patients (with or without ALS). The ALS patients in the study already benefit from routine medical care in ALS expert centers in France. . The patients concerned by the study are managed without modification of the care pathway, no modification of the therapeutic indications, no modification of the diagnostic examinations or follow-up necessary according to the context, which are carried out according to the recommendations of the HAS.

You may qualify if:

  • Patient over 18 years of age,
  • Patient from one of the 2 study populations:
  • Diagnosis of definite or probable ALS according to El Escorial criteria ("patients ALS" group) ;
  • Control group
  • Patient able to carry out a mouth rinse,
  • Patient affiliated to the healthcare system,
  • Patient has dated and signed the consent form,

You may not qualify if:

  • Recent (\<1 month) or ongoing bacterial or viral infection,
  • Known active oral or digestive mycosis,
  • Evolving, symptomatic or obvious oral pathology,
  • Known pregnancy,
  • Patient participating in another clinical research study,
  • Patient deprived of liberty by administrative or judicial decision or under guardianship ;
  • Subject refusing to take a saliva sample;
  • For the control group: direct relationship (siblings, descendants, ascendants) with a patient included in the study;
  • For control group: medical history of neurological disease (excluding migraine).
