J Med Genet. 1990 Dec;27(12):782-3. doi: 10.1136/jmg.27.12.782.

Abstract

We report a 3 month old boy with tetraploidy, found in peripheral blood and skin fibroblast cultures, with severely delayed growth and neurodevelopment, and with a cleft lip; these findings have not been described before. This report brings to seven the total number of liveborn infants with a 92,XXYY karyotype.
