We present a 16-month-old boy with developmental delay, minor anomalies, small penis, and lymphedema of the upper limbs. Routine cytogenetic analysis suspected a duplication of 5q. Fluorescent in situ hybridization (FISH) with a cosmid probe (MCC at the 5q22 APC region) showed tandemly duplicated fl

✦ Synopsis
A 20-year-old man with multiple anomalies caused by a de novo duplication of the long arm of chromosome 1 is presented. The patient suffers from severe mental retardation, epilepsy, bronchial stenosis, and minor anomalies (e.g., hirsutism, midface dysplasia, and beaked nose). A G-banding analysis of the patient's chromosomes showed additional segments in chromosome 1. Fluorescent in situ hybridisation analysis with a chromosome 1 painting probe showed that the extra material originated from chromosome 1. Further analysis with cosmid probes demonstrated that the region involving chromosome bands 1q31 to q41 is present in a tandem duplication. Am.
