We report a 40-year-old female with mild mental retardation and behavior problems and her 6-year-old daughter. Chromosome analysis showed that both patients had a proximal duplication in the short arm of chromosome 16. The aberration was characterized further with band-specific probes, resulting in a 46,XX,dir dup(16)(pter→p11.2::p12.1→qter) karyotype. The clinical and cytogenetical findings are compared to other patients with partial trisomy 16p reported in the literature.
