DNA methylome, R-loop and clinical exome profile of patients with sporadic Amyotrophic Lateral Sclerosis (RRBS)

Project description:Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disorder characterised by the death of motor neurons, the aetiology of which is essentially unknown. Here, we present an integrative epigenomic study in blood samples from seven clinically characterised sporadic ALS patients to elucidate molecular factors associated with the disease. We used clinical exome sequencing (CES) to study DNA variants, DNA-RNA hybrid immunoprecipitation sequencing (DRIP-seq) to assess R-loop distribution, and reduced representation bisulfite sequencing (RRBS) to examine DNA methylation changes. The above datasets were combined to create a comprehensive repository of genetic and epigenetic changes associated with the ALS cases studied. Our data descriptor is expected to guide further mechanistic studies on ALS to discover underlying genetic causes and develop new epigenetic therapies to combat this life-threatening disease.
