This study aimed to examine gene mutations associated with familial (FALS) and sporadic (SALS) amyotrophic lateral sclerosis (ALS) within a diverse population in Brazil.
Researchers analyzed specific genes (C9orf72, TARDBP, SOD1, FUS, VAPB) in a sample of 39 FALS and 189 SALS patients, finding a significantly higher mutation rate in FALS patients (61.3%) compared to SALS patients (5.3%).
Key findings included prevalent mutations in C9orf72, VAPB, and SOD1 among FALS patients, with some SALS patients also showing C9orf72 mutations, while no FUS mutations were detected in
