NCT06595212

Brief Summary

The goal of this study is to learn from discordant twins affected by Amyotrophic Lateral Sclerosis and/or Frontotemporal Dementia the contribution of genetic background versus environmental exposure. The main questions it aims to answer is:

  • How far does the genetic background explain the onset of ALS/FTD in discordant twins?
  • Which environmental factors and events occurring in post-fetal life influence the onset or progression of this neurodegenerative condition? Participants with ALS and/or FTD with a monozygotic or dizygotic twin willing to contribute to this research will be followed up for two years by specialized Motor Neuron Disorders centers in Italy, donating biological specimen for -omic sciences analysis, and checking out if prodromal signs/symptoms of these two conditions will develop during time.

Outcome Measures

Primary Outcomes (1)

  • Environmental/genetic risk/protective factors involved in driving discordance in monozygotic (MZ) twins

    Using a multi-omic approach, the investigators will establish a longitudinal cohort of Italian twins affected by ALS/FTD, collecting various samples to compare affected and unaffected twins across multiple biological and phenotypic variables. The aim is to uncover the factors underlying discordance in monozygotic twins, identifying what protects the unaffected twins and what predisposes the affected ones.

    24 months

Study Arms (2)

affected twins

Other: multiomic profile to assess genetic and environmental risk factiors

unaffected twins

Other: multiomic profile to assess genetic and environmental risk factiors

Interventions

Genomic, epigenetic, proteomic, microbiome, immunology, biomarker, metabolite, pesticide, metal, and metalloid investigations will be conducted. The twins will be followed longitudinally from a clinical perspective, with biological sample collections to assess discordance and identify early disease signatures in unaffected individuals.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study population include all Italian participants with ALS and/or FTD who have a mozygotic or dizygotic twin with (concordant) or without (discordant) the same condition willing to participate in the study. Once the consent is obtained, the twins will be followed up for 24 months in three possible Italian recruiting centres (Modena, Turin, Palermo).

You may qualify if:

  • Age \>18 yrs
  • Presence of MZ or DZ twins in the family both willing to participate in the study and able to provide informed consent
  • At least one twin is affected by ALS as defined by Gold Coast Criteria (Shefner et al., 2020) and/or by FTD as defined by Strong and colleagues (Strong et al., 2017)
  • Subjects able and willing to comply with study procedures as per protocol
  • Subjects able to understand, and capable of providing informed consent at screening visit before any protocol-specific procedures

You may not qualify if:

  • Unwillingness to perform assessments as stated in the protocol at least during baseline visit for both twins
  • Unwillingness to donate biological samples collected at periphery (lumbar puncture excluded) for both twins
  • Women who are pregnant or breastfeeding
