Trisomy in the distal end of the long arm of chromosome 3. A condition clinically similar to the Cornelia de Lange syndrome

L. J. Sciorra, K. Bahng and M. L. Lee

A patient had a trisomy for the distal portion of the third chromosome. The major clinical features were failure to thrive, profound mental retardation, dysmorphic head shape, a short nose, anteverted nares, long eyelashes, synophrys, characteristic mouth, and short stature. The similarities between the clinical picture and the Cornelia de Lange syndrome are very striking.
