A female patient with partial duplication 22 (q13-->qter).
We report on a 9-month-old female patient with pre- and postnatal growth retardation, hypertelorism, bilateral cleft lip and palate, and a peripheral pulmonary stenosis. High resolution banding and fluorescent in situ hybridization (FISH) revealed a de novo partial trisomy 22q13-qter. We compare the clinical findings to published patients with this rare chromosomal aberration and discuss the chromosomal differential diagnosis. Facial features at first sight suggestive of Wolf-Hirschhorn syndrome may be an additional, previously undescribed clinical sign in some patients with partial trisomy 22q.
