Partial duplication of the short arm of chromosome 9 (p13→p22) in a child with typical 9p trisomy phenotype

Abstract
A 3-year-old girl with duplication 9 (p22→p13) is reported. The presence of a classical 9p trisomy phenotype in this patient suggests that this region (or part of it) is responsible for the major, typical clinical stigmata of this partial autosomal trisomy syndrome.
