  • Variants previously associated with ALS are shown in bold.

  • *Gene conventionally associated with recessively inherited ALS.

  • D—Variant may cause disease in a dominant fashion and carrier frequencies relate to heterozygote carriers.

  • R—Variants may cause disease in a recessive fashion and carrier frequencies relate to homozygous carriers.

  • NR—Variant not reported within either the 1000 genomes or ESP6500 datasets (samples of European ancestry=4679, total number of samples=7595).

  • ALS2—ENST00000264276; FUS—ENST00000254108; OPTN—ENST00000263036; SETX—ENST00000224140; TARDBP—ENST00000240185; VCP—ENST00000358901.

  • ALS, amyotrophic lateral sclerosis; ESP, Exome Sequencing Project.
