Summary
A case of de novo trisomy 9p was observed. Cytogenetic analysis of G-, R-, Q-, and C-banded preparations revealed a karyotypic description of 47,XY,+del(9)(pter→q13). In addition to the principal characteristics of the 9p trisomy syndrome, the child presented with skeletal and urogenital abnormalities. It appears that certain clinical abnormalities are due to trisomy of 9q1.
