Amyotrophic lateral sclerosis (ALS) is the most common form of motor neuron disease. We describe the case of a patient with a rapidly progressive form of ALS characterized by both upper and lower motor neuron impairment, no early bulbar signs and severe pain in all four extremities. The patient had a heterozygous c.271G > A mutation in SOD1, leading to an amino acids substitution of asparagine to aspartate at position 90 of the protein chain (p.D90N). Our report confirms that ALS patients with D90 codon heterozygous mutations may be associated with rapid progression and a prominent pain syndrome.

Abstract

Amyotrophic lateral sclerosis (ALS) is the most common form of motor neuron disease. We describe the case of a patient with a rapidly progressive form of ALS characterized by both upper and lower motor neuron impairment, no early bulbar signs and severe pain in all four extremities. The patient had a heterozygous c.271G > A mutation in SOD1, leading to an amino acids substitution of asparagine to aspartate at position 90 of the protein chain (p.D90N). Our report confirms that ALS patients with D90 codon heterozygous mutations may be associated with rapid progression and a prominent pain syndrome.
