We report on a female infant with partial trisomy 9p (pter→p13) and partial trisomy 14q (pter→q22) resulting from a 3:1 segregation of a maternal reciprocal translocation (9;14)(p13;q22). Both trisomy 9p and partial trisomy 14q have been described as recognized phenotypes with characteristic pattern

✦ Synopsis
An 8-year-old boy with partial trisomy 14q and phenotype distinct from previously reported cases is described. The mother carries a balanced 9;14 reciprocal translocation. The patient presented with minor facial anomalies, developmental delay, hyperphagia, and obesity. Imprinting of maternal chromosome 14 or disruption of one or more genes on chromosome 9 may be responsible for our patient's manifestations.

The use of the adjective "identical" rather than monozygotic leads to misunderstandings about the biology of monozygotic twinning. Most monozygotic twin pairs are not identical; there may be major discordance for birth weight, genetic disease, and congenital anomalies. These indicate that postzygoti
