Partial trisomy of the short arm of chromosome 4 is considered to be a rare chromosomal disorder. Its clinical and dermatoglyphic features tend to make it a clinically recognizable syndrome. This paper describes a 2 year-old female child with the characteristic findings of frontal bossing, deep-set eyes, broad nasal bridge giving the appearance of hypertelorism, wide nares, midfacial hypoplasia, large dysplastic ears, prognathism and various hand and foot malformations. Chromosomal studies showed her to be trisomic for the distal two-thirds of the short arm of number 4. The etiology of this chromosomal aberration in most instances is unknown, but may occur as a result of an unbalanced translocation in one of the parents as in the case reported here.
