Understanding genetic and observable traits in neurodegenerative diseases

Phenotype, Genotype and Biomarkers 2

Observational University of Miami · NCT04875416

This study is trying to see how the symptoms and genetic information of people with ALS and similar diseases are connected, while also looking for possible markers that could help us understand these conditions better.

What this trial studies

This observational study aims to explore the connections between the observable symptoms (phenotype) and genetic information (genotype) in patients with amyotrophic lateral sclerosis (ALS) and related neurodegenerative conditions such as frontotemporal dementia (FTD), primary lateral sclerosis (PLS), hereditary spastic paraplegia (HSP), and progressive muscular atrophy (PMA). The study will also focus on identifying potential biomarkers associated with these diseases. Participants will include individuals diagnosed with these conditions and their biological family members, allowing for a comprehensive analysis of genetic and phenotypic data.

Who should consider this trial

Good fit: Ideal candidates include individuals with a clinical diagnosis or suspicion of ALS or related disorders.

Not a fit: Patients with confounding neurological, psychological, or medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of neurodegenerative diseases, potentially leading to improved diagnostics and targeted therapies.

How similar studies have performed: Other studies have shown promise in linking genotype and phenotype in neurodegenerative diseases, suggesting a potential for success in this approach.

* Family member of an enrolled affected primary participant

Exclusion Criteria for biological family members (secondary participants) include:
