This report describes a family in which eight individuals in three generations had mental retardation in association with a characteristic pattern of clinical problems and physical abnormalities including short stature, eczema, hernias, delayed puberty, dysmorphic facies and digital anomalies. The family history was consistent with a chromosomal rearrangement with transmission through balanced carriers. Routine ASG banding studies showed extra chromosomal material on a chromosome 16 but failed to demonstrate any differences between the affected individuals and the presumed carriers. However, subsequent studies utilizing trypsin banding and microspectrophotometry of individual chromosomes demonstrated that the affected individuals were partially trisomic for the distal band of the long arm of chromosome 5 and that 0.273 units of a chromosome 5 were translocated to chromosome 16. This definitive cytogenetic diagnosis permitted accurate prenatal diagnosis to be carried out on the fetus of a balanced carrier female. The application of these techniques to previously obscure familial dysmorphic syndromes is recommended.

D008607 Intellectual Disability Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.
