Abstract
Chromosome analysis in a newborn, the daughter of diabetic parents, who showed multiple dysmorphic signs and malformations revealed direct duplication of a long arm segment of chromosome 3 (3q2100→3q2700). Both parents have normal karyotypes. Compilation of the phenotype stigmata with those of 7 other patients and 1 fetus with partial trisomy 3q confirmed that clinical recognition of this syndrome is possible. It is characterized by hypertrichosis, typical craniofacial dysmorphia, frequent organ malformations and skeletal anomalies, as well as a peculiar dermatoglyphic pattern. It is a severe genetic disturbance, leading to death in the first months of life in many cases and only symptomatic care is advised.
