Abstract

Wolf-Hirschhorn syndrome is caused by a partial loss of the distal short arm of chromosome 4. Characteristic clinical features are severe growth retardation, mental retardation, seizures, congenital cardiac defects, urogenital abnormalities, microcephaly, hypertelorism, prominent glabella, cleft lip and palate and micrognathia. In 87% of cases, chromosome 4 deletion arises as a de novo event, whereas in the remaining cases it is derived from a familial balanced translocation. Chromosomal study of the patient showed 46 XX der(4)t(4;18)(p15.2;q23), and the patient's mother was found to have a balanced translocation, 46 XX t(4;18)(p15.2;q23).
