Description

Principal Investigator: Richard K. Wilson, Ph.D, The Genome Institute, Washington University School of Medicine, St. Louis, MO, USA MeSH: Amyotrophic Lateral Sclerosis https://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?study_id=phs000831 Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that affects the nerves in the brain and spinal cord, leading to muscle weakening and eventual paralysis and death. Ten percent of ALS cases are thought to be familial while the majority of cases are sporadic and the causative factors unknown. Dr. Roger Pamphlett of the University of Sydney has collected a unique cohort of consented trios where the child has ALS but the parents are unaffected. Since the age of onset is so late, it is very difficult to obtain this kind of trio. We have performed whole exome sequencing on these trios to identify *de novo* and recessive germline variants associated with sporadic ALS. In addition, Dr. Pamphlett has assembled a collection of consented discordant monozygotic twins, where one twin has ALS and the other is unaffected. We performed whole genome sequencing on these twin pairs to identify postzygotic variants that may contribute to sporadic ALS susceptibility. Finally, we have the opportunity to compare the sequence and gene expression in affected and unaffected tissues from blood, brain and/or spinal cord samples from consented ALS patients to look for somatic mutations or gene expression changes that may further our understanding of the disease.
