✦ Synopsis


We report on a boy with proximal interstitial deletion of chromosome 4, del(4)(q21. 22q23). The patient was born at term with a low birth weight, flat nasal bridge, micrognathia, wide-spaced nipples, clinodactyly of fifth fingers, overlapping fingers, postaxial polydactyly of the right foot, micropenis, hypospadias, a dermal sinus, and cardiac malformations. He developed psychomotor retardation, seizures, and a liver t u m o r w i t h a n i n c r e a s e d s e r u m ␣fetoprotein level and rapid growth. The patient carried a deletion of chromosome 4 involving the 4q21-q22 region that was reported to form a unique syndrome. The absence of central nervous system overgrowth and the presence of a malignant liver tumor are unique to our patient, compared to others with the 4q21-q22 deletion syndrome. The clinical manifestations and relationship between the liver tumor and chromosomal anomaly are discussed. Am. J.

A 17-year-old boy who was diagnosed with ''Waardenburg syndrome'' showed moderate growth and mental retardation. Chromosome analysis showed an apparent interstitial deletion 4q12q21.1. The mother had a direct insertion of the deleted segment into a chromosome 8. The rearrangement was confirmed to be
