Abstract
BACKGROUND
Pure partial trisomy of chromosome 5q is rare and cases have ranged over the entire region, making it difficult to describe a good phenotypic correlation to the cytogenetic duplication.
CASE
We present a 4.5βyearβold girl with a de novo direct duplication of chromosome 5q15βq23.2. She has moderate developmental delay with lack of speech, microcephaly, and subtle dysmorphic features including prominent forehead, bulbous nose, epicanthic folds, protruding tongue, and slightly posteriorlyβrotated ears.
CONCLUSIONS
A comparison is made with other similar duplication cases reported in the literature and a general description of a proximal 5q duplication phenotype is given, with lack of speech as the principal feature. Birth Defects Research (Part A), 2006. Β© 2006 WileyβLiss, Inc.

## Abstract We report on a 3βyearβold boy with moderate developmental delay, abnormal craniofacial features and ventricular septal defect resulting from trisomy of the long arm of chromosome 20. The cytogenetic defect consists of a de novo isolated interstitial duplication in distal 20q [dup(20)(q1
## Abstract We report on a 20βmonthβold boy with duplication of the distal part of 19q. His karyotype is 46, XY, β22, + der(22), t(19;22) (q13.3; p11.2)mat. The propositus has multiple minor anomalies, congenital heart defects, seizures, profound psychomotor retardation, and growth impairment. Thes
We report on a patient with primordial growth retardation, mental retardation, and minor anomalies (triangular face, open sagittal suture, frontal bossing, telecanthus, upturned nose, micrognathia, and small mouth with downturned corners). The diagnosis of Russell-Silver syndrome (RSS) had been cons
