Amyotrophic lateral sclerosis 2

ALS2, Alsin
The protein encoded by this gene contains an ATS1/RCC1-like domain, a RhoGEF domain, and a vacuolar protein sorting 9 (VPS9) domain, all of which are guanine-nucleotide exchange factors that activate members of the Ras superfamily of GTPases. The protein functions as a guanine nucleotide exchange factor for the small GTPase RAB5. The protein localizes with RAB5 on early endosomal compartments, and functions as a modulator for endosomal dynamics. Mutations in this gene result in several forms of juvenile lateral sclerosis and infantile-onset ascending spastic paralysis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008] (from NCBI)

Kim et al., South Korea. In Neurobiol Aging, Jan 2016
Using this technique, we tried to identify mutations in 4 index patients with familial ALS and 148 sporadic ALS in Korean population and identified 4 known mutations in SOD1, ALS2, MAPT, and SQSTM1 genes, respectively, and 28 variants of uncertain significance in 9 genes.

New
Cigan et al., Douai, France. In Plant Physiol, Oct 2015
DNA vectors expressing maize codon-optimized Streptococcus pyogenes Cas9 endonuclease and single guide RNAs were cointroduced with or without DNA repair templates into maize immature embryos by biolistic transformation targeting five different genomic regions: upstream of the liguleless1 (LIG1) gene, male fertility genes (Ms26 and Ms45), and acetolactate synthase (ALS) genes (ALS1 and ALS2).
Mutations in SOD1 and FUS caused juvenile-onset sporadic amyotrophic lateral sclerosis with aggressive progression.

Review
Simmons et al., United States. In Muscle Nerve, 2014
Mutations in a large number of genes, including SOD1, C9ORF72, TARDBP, FUS, VAPB, VCP, UBQLN2, ALS2, SETX, OPTN, ANG, and SPG11, are thought to cause ALS, whereas others, including ATAXN2, GRN, HFE, NEFH, UNC13A, and VEGF, appear to be disease-modifying genes.

BACKGROUND: Infantile-onset ascending hereditary spastic paralysis (IAHSP) is a rare, early-onset autosomal recessive motor neuron disease associated with mutations in ALS2.

Review
Burgunder et al., Vienna, Austria. In Eur J Med Genet, 2014
Juvenile fALS is most frequently caused by mutations in ALS2, SETX, spatacsin, or Sigmar1 and adult fALS by mutations in C9orf72, SOD1, TARDBP, and FUS.
