Abstract:
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.

Gene Duplication and Divergence
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
