Notes
rs333662 is one of 6 SNPs found upstream of an (uncharacterized) gene known as FLJ10986 that have been found to be overrepresented in 1,152 patients with sporadic amyotrophic lateral sclerosis (ALS). A study involving a large case-control series from the Netherlands, Belgium, Sweden and Ireland (total: 1883 sporadic ALS patients and 2063 controls) found no significant association between sporadic ALS and the six previously reported associated SNPs, including this one.
