The anesthetic management of a patient with chromosome 10qter deletion syndrome

A subterminal deletion of the long arm of chromosome 10: a clinical report and review

We report on a girl with mental retardation, dysmorphic features, and behavioral problems. A small terminal deletion of the long arm of chromosome 10 was detected by subtelomeric fluorescence in situ hybridization (FISH) studies in all analyzed metaphases. The deletion was shown to be a de novo terminal deletion of approximately 6.1 Mb, with the deletion breakpoint localized at band 10q26.2, between BAC probes RP11-498K22 and RP11-42K2. A subterminal 10q deletion as found in the present patient has, to our knowledge, only been reported in 15 patients (including 8 familial cases). We review the clinical and behavioral phenotype of these patients with "pure" subterminal 10q deletion.
