title: [Clinical features of one of the syndromes associated with oligophrenia--the so-called "elf face"].
abstract: The authors give a clinical description of 19 patients from 2 years and 10 months-18 years with "elf face" syndrome. The most prominent traits of the disease were a specific look of the face, congenital heart insufficiency, muscular hypotonia, inguinal hernia. The mental state was characterized by an expressed mental retardation with some special traits: relatively well developed speech, talkativeness, good-naturedness, an euphoric mood, inactivity and poor motor functioning. In 3 patients who were older a psychopath-like syndrome was found. A study of the kariotype in 5 cases depicted hetermorphism of homologues in some pairs of chromosomes in more than 10% of the cells as well as an increased amount of structural reconstructions. Indirect calculation have shown that the incidence of the syndrome is approximately equal to 1:25000 births which is significantly more than cited in literature.
