Interstitial deletion of chromosome 7p detected antenatally.

An interstitial deletion in chromosome 7(p13p15) detected in amniotic fluid cells is presented. After termination, the fetus was noted to have an asymmetrical skull, low set ears, a flattened nose, bifid thumbs and right big toe, pyloric adenomyosis, hypospadias, and simian creases. A brief comparison is made with previously reported cases involving deletions of 7p, including those associated with craniosynostosis.
