ABSTRACT

Congenital myasthenic syndromes (CMS) are rare diseases caused by mutation in genes coding for proteins involved in neuromuscular junction structure and function. DPAGT1 gene mutations are a rare cause of CMS whose clinical evolution and pathophysiological mechanisms have not been clarified completely. We present the case of two twins displaying an infancy-onset predominant limb-girdle phenotype and carrying a novel DPAGT1 mutation associated with unusual histological and clinical findings. CMS can mimic paediatric and adult limb-girdle phenotype, hence neurophysiology plays a fundamental role in the differential diagnosis.
