Abstract

Seipinopathy is an autosomal dominant neurodegenerative disease caused by mutations of the Berardinelli-Seip Congenital Lipodystrophy 2 (BSCL2) gene. We report the first Japanese case of seipinopathy with a heterozygous mutation of p.N88S in the BSCL2 gene. The patient showed bilateral hyperreflexia of the biceps, triceps, brachioradialis, and knee, as well as the pes cavus and distal dominant weakness and atrophy of both arms and legs, suggesting the involvement of both upper and lower motor neurons. Mutations of the BSCL2 gene have been known to cause motor neuron degeneration through endoplasmic reticulum stress. Seipinopathy should be considered in patients with symptoms mimicking amyotrophic lateral sclerosis.
