Charcot-Marie-Tooth disease and schizophrenia in identical twins

Charcot-Marie-Tooth disease and schizophrenia occurred in monozygotic twins. Dermatoglyphics and blood grouping determined monozygocity. Charcot-Marie-Tooth disease appeared to be an autosomal dominant trait transmitted from the mother. No definite evidence of inheritance was seen for schizophrenia.
