Alexithymic characteristics were studied in 15 monozygotic and 18 like-sex dizygotic healthy young twin pairs in a semistructured interview. Variance analysis showed larger within-pair variances in the dizygotic than in the monozygotic twins. With some reservations, these results point to a genetic influence on the etiology of the alexithymic phenomenon.
