SARM1 and amyotrophic lateral sclerosis: This included genes such as DCC, which encodes the netrin-1 receptor and has an important role in the development of the nervous system (p = 4.29 × 10−11 with neuroticism), as well as SARM1, which has been previously implicated in axonal degeneration (p = 1.76 × 10−08 with amyotrophic lateral sclerosis).
