Identification of an A4V SOD1 mutation in a Chinese patient with amyotrophic lateral sclerosis without the A4V founder effect common in North America.

Abstract excerpt

We identified a missense alanine to valine mutation at codon 4 (A4V) in the Cu/Zn superoxide dismutase (SOD1) gene in a 51-year-old male of Chinese origin with familial amyotrophic lateral sclerosis (ALS). The patient displayed a typical A4V-related phenotype that included rapid progression and predominant lower motor neuron involvement. This patient is the first such carrier reported outside Caucasian ALS...
