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.

Diagnosis of lipogranulomatosis (Farber disease) by use of cultured fibroblasts.

The enzyme defect in Farber disease, a deficiency of acid ceramidase, has been demonstrated in cultured skin fibroblasts, which provides a means of confirming the diagnosis during life. The assay can also be performed using cultured amniotic fluid cells and is a potential tool for detection of carriers of the disease.

48, XXXY Klinefelter syndrome and nail-patella syndrome in the same child.

A patient is described who in addition to having the 48, XXXY Klinefelter syndrome has the autosomal dominant nail-patella syndrome, inherited through his mother from the grandfather. Clinical signs of both syndromes were found. Chromosomal investigation with BUDR incorporation and acridine orange staining showed that one X chromosome stained intensively, while the other X chromosomes were elongated and weakly stained. Difference in degree of stretching of the supernumerary chromosomes was noted. The occurrence of the two rare syndromes in the same patient is assumed to be fortuitous.

Trisomy 9p in a patient with a de novo 9/15 translocation.

Mental retardation, facial dysmorphism, hypertelorism, antimongoloid eye slants, epicanthus, globular nose, malformed ears, bone abnormalities, one flexion crease on 5th finger, simian crease, and speech difficulties with delayed expressivity were found in a girl with trisomy of the short arm of chromosome 9. The 9p+ syndrome was due to a sporadic translocation of the short arm of chromosome 9 onto the short arm of chromosome 15.

Translocation (13q21q). Four generation family study with analysis of satellite associations, fluorescent markers, and prenatal diagnosis.

A (13q21q) translocation was found in an infant with Down's syndrome. The 17-year-old mother and the grandmother carried the translocation 45,XX,t(13;21)(p12;q11). The great grandparents had normal karyotypes. Fluorescence marker studies suggested that the translocation originated in the great grandmother. The hypothesis was supported by satellite association studies which showed a significant excess of 13-21 and 13-15 associations in the great grandmother.
