[Polymorphism of Charcot-Marie-Tooth neural amyotrophy in uniovular twins]

The paper is concerned with a description of an atypical clinical picture of Charcot-Marie-Tooth neuronal amyotrophy in 2 eight-year old monozygotic twins. The traits of the disease were characterized by a deformation of the feet, mild cerebellar symptoms, development of ptosis and other myopathical symptoms, an enlargement of the transversal nerve of the neck and a distribution of the process to the proximal parts. The diagnosis was confirmed by EMG studies. The authors detected a large amount of abortive signs in many members of the family both along the mothers, as well as fathers line. This observation demonstrates clinical and genetical polymorphism of neuronal amyotraphy.
