A case report of a de novo tandem duplication (5p) (p14 → pter)

Abstract
The case described in this paper represents on the basis of cytogenetic evidence, the first reported example of a de novo tandem dup(5p)(p14→pter). Clinical changes were minimal, unlike previously described cases in which more complex structural chromosomal changes were involved and a phenotype was provisionally attributed to dup(5p) (p14 → pter). The duplicated segment of minimal effect identified in this case involved more than five eighths of 5p. It is proposed that there is a localised critical segment elsewhere on the short arm of chromosome 5 (p11–p13), which when duplicated is of greater significance in terms of clinical effects.
