SOD1, which codes for superoxide dismutase 1, is the second most common gene associated with ALS and causes about 12% of familial cases and about 2% of sporadic cases. [6] More than 150 mutations in SOD1 have been described, almost all of which have an autosomal dominant mode of inheritance. [8]
SOD1 binds copper and zinc ions and is one of three superoxide dismutases responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic and mitochondrial intermembrane space protein, acting as a homodimer to convert naturally occurring, but harmful, superoxide radicals to molecular oxygen and hydrogen peroxide.
A recent example had used iPSC of patient with SOD1 dominant mutation and they studied the motor neurons derived from the patient, and they found that the functional genes and the ER stress regulating genes of the mitochondria were reduced in SOD1 patients, similar to the effect of C9orf72 mutation on the patients.

The Foundation was founded by Les Turner, a Chicago businessman, and his family after he was diagnosed with amyotrophic lateral sclerosis (ALS) in 1976. [4] Les Turner serves nearly 90 percent of ALS patients in the Chicago metropolitan area. [5] In 1979, the Les Turner ALS Research Laboratory was opened at Northwestern Medicine. Then, in 1986 ...
An ALS mouse model through gain-of-function mutations in SOD1 has been developed. [50] c9orf72 A gene called c9orf72 was found to have a hexanucleotide repeat in the non-coding region of the gene in association with ALS and ALS-FTD. [51] These hexanucleotide repeats may be present in up 40% of familial ALS cases and 10% of sporadic cases.
Nearly 2.3 million people are estimated to be living with multiple sclerosis around the world, but when Montel Williams received his official diagnosis back in 1999, not much was known about the ...
Tofersen was developed by Ionis Pharmaceuticals and was licensed to, and co-developed by, Biogen. [7] [8]The effectiveness of tofersen was evaluated in a 28-week, randomized, double-blind, placebo-controlled clinical study in 147 participants with weakness attributable to amyotrophic lateral sclerosis and a superoxide dismutase 1 (SOD-1) mutation confirmed by a central laboratory.

A cousin was diagnosed and died in 1997; he was 21 years old. During six-week period in 2002 his mother, grandmother and aunt all died. Fifty per cent of Yerbury's family carry a faulty SOD1 gene. His youngest sister died from MND at 26 years old. Yerbury and his sister, Naomi, were tested for the gene; Naomi was clear but Yerbury's test was ...
