Abstract:
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by the death of motor neurons. To date, more than 20 genes have been implicated in ALS, and of these, the 2 most frequently mutated are the superoxide dismutase 1 (SOD1) gene and the chromosome 9 open reading frame 72 (C9ORF72) gene. In this study, we aimed to investigate the contribution of these 2 Mendelian genes to the development of the disease in Hungarian ALS patients (n = 66). Direct sequencing of the SOD1 gene revealed a novel (p.Lys91ArgfsTer8) and 3 recurrent heterozygous mutations (p.Val14Met, p.Asp90Ala, and p.Leu144Phe) in 5 patients. The novel p.Lys91ArgfsTer8 mutation led to a frameshift causing the addition of 8 new amino acids, including a premature stop codon at position 99. The GGGGCC hexanucleotide repeat expansion of the C9ORF72 gene was present in 1 ALS patient. This study represents the first genetic analysis of 2 major ALS causative genes in a cohort of Hungarian ALS patients and contributes to the further understanding of the genetic and phenotypic diversity of ALS.
