Disease pattern among 942 mentally retarded persons in a Danish county.

An analytical description is presented of 942 mentally retarded persons from the county of West Zealand. The prevalence of mental retardation (i.e. persons who were registered with an IQ below 75) was 0.36%. Almost half of the patients were living in institutions. Of the patients 43% were women and 57% men. Important aetiological factors are listed. In almost one third of the patients, similar cases were present among the closest relatives; 30% of the patients were born as the fourth or subsequent child in the family; one sixth of the mothers were more than 35 years old at the birth of the handicapped child. Twenty-two percent of the patients with IQs below 50 had Down's syndrome. Seventeen percent of the patients had epilepsy had 11% cerebral palsy. In the central institution all patients had psychiatric or somatic complications.

Small metacentric nonsatellited extra chromosome: report of five mentally retarded individuals and review of literature. Contribution to further delineation of a new syndrome.

Five mentally retarded male patients with a supernumerary small metacentric nonsatellited chromosome were found to have many clinical features in common. The face showed characteristic small crowded features, the bodily habitus was asthenic, and the hands and feet had minor abnormalities. Renal anomalies were present in two patients. One patient had a myelomeningocele. Cytogenetic studies employing Q, R, and C banding in four patients showed the small extra chromosome to have staining properties compatible with an isochromosome of the short arm of chromosome 18. A comparison with previous case reports suggests a new syndrome. However, the identity of the extra chromosome has not yet been determined.
