A child with monosomy for the distal part of the short arm of chromosome 3 is presented. Altered features include prenatal onset growth deficiency, postaxial polydactyly, ptosis, ear anomalies, and a triangular facial appearance. In addition to generalised delay in psychomotor development, specific problems in visual attention were present. Comparison with the previously reported case suggests that the phenotype observed constitutes a clinically recognisable pattern of malformation.
