โฆ Synopsis
Partial trisomy (interchromosomal duplication) of the short arm of chromosome No. 12 was observed in an infant girl with psychomotor retardation, prominent forehead, ptosis of the right eyelid, esotropia/exotropia, flat nose, hypotonia and other anomalies. A comparison of her features with those in five reported cases with a similar chromosomal imbalance shows certain features common to all, but the material is too limited for definitive characterization of a trisomy 12p syndrome.
