Brachydactyly in a child with duplication-deficiency subsequent to t(15;20)(q25.2;p12.2)mat. Candidate regions on one or both chromosomes?
We report a child with a duplication-deficiency subsequent to t(15;20)(q25.2;p12.2), transmitted in at least 5 generations, who showed features of 15q- syndrome. We speculate that brachydactyly--most likely because of brachymesophalangism--is a feature of the phenotype of this chromosomal aberration and points to candidate gene(s) in this region. A similar brachydactyly was, however, reported with dup(20p1-pter).
