Acampomelic campomelic dysplasia with de novo 5q;17q reciprocal translocation and severe phenotype

J Med Genet. 1998 Jul;35(7):597-9. doi: 10.1136/jmg.35.7.597.

Abstract

Campomelic dysplasia (CD) is a rare skeletal malformation syndrome caused by mutations in the SRY related gene SOX9, mapped to 17q24.3-q25.1. A small proportion of cases are associated with structural rearrangements involving 17q and it has been proposed that this subgroup have a milder phenotype and better prognosis compared to those with mutations in the SOX9 gene. We report a severely affected infant with the acampomelic form of campomelic dysplasia, who died at 11 days and was found to have a de novo reciprocal translocation, 46,XX,t(5;17)(q15;q25.1). This is the second reported case of severe campomelic dysplasia associated with a structural rearrangement involving 17q and suggests that this subgroup of patients may not significantly differ from those without chromosomal rearrangements with regards to phenotype or prognosis.
