Mutations of the lipid phosphatase FIG4 that regulates PI (3, 5) P 2 are responsible for the
recessive peripheral-nerve disorder CMT4J. We now describe nonsynonymous variants of
FIG4 in 2%(9/473) of patients with amyotrophic lateral sclerosis (ALS) and primary lateral
sclerosis (PLS). Heterozygosity for a deleterious allele of FIG4 appears to be a risk factor for
ALS and PLS, extending the list of known ALS genes and increasing the clinical spectrum of
FIG4-related diseases.
