Rubinstein-Taybi syndrome with de novo reciprocal translocation t(2;16)(p13.3;p13.3).
We describe a girl with typical Rubinstein-Taybi syndrome with apparently balanced reciprocal translocation between chromosome 2 and 16. The patient has a condition characterized by mental retardation, typical facial manifestations, broad thumbs and first toes. Cytogenetic studies of the patient showed a reciprocal translocation without visible deletion, karyotype: 46,XX, t(2;16)(p13.3;p13.3). Her parents had normal chromosomes. These results suggest that the locus of the gene for the Rubinstein-Taybi syndrome may be situated at 2p13.3 or 16p13.3.
