Patients with deletions of 9q22q34 do not define a syndrome: three case reports and a literature review.

Three children with deletions involving the 9q22q34 region are described. A review of clinical features of these three new patients and seven previously reported ones did not demonstrate a recognizable dysmorphic pattern. Our cases illustrate the need for repeat karyotyping at higher levels of resolution when there is a suspicion of a chromosome anomaly, since each deletion was missed on initial analysis.
