An anonymous reader writes: Researchers are crediting the ALS Ice Bucket Challenge, a fundraiser for amyotrophic lateral sclerosis that went viral in 2014, for funding a new study that has possibly identified a common gene that contributes to the nervous system disease. Yahoo reports via Good Morning America: "In a study published in The Nature Genetics Journal, researchers from various institutions, including the University of Massachusetts Medical School and the University Medical Center Utrecht, identified the gene NEK1 as a common gene that could have an impact on who develops the disease. Variants of the gene appear to lead to increased risk of developing ALS, according to preliminary findings. Researchers in 11 countries studied 1,000 families in which a family member developed ALS and conducted a genome-wide search for any signs that a gene could be leading to increased ALS risk. After identifying the NEK1 gene, they also analyzed 13,000 individuals who had developed ALS despite no family history and found they had variants in that same gene, again linking that gene with increased ALS risk. Starting in the summer of 2014, the ALS Ice Bucket Challenge led to 17 million videos made and $220 million raised, according to the ALS Association -- $115 million of which went to the association."
