De novo complex autosomal translocation involving chromosomes 8, 13 and 15 in a girl with a sporadic retinoblastoma

Abstract
We report a case of a 5-month-old female with sporadic monolateral retinoblastoma (RB) with a constitutional de novo complex autosomal translocation involving chromosomes 8, 13 and 15 resulting in a deletion of chromosome 13q14 confirmed by esterase D assay. The translocation of the terminal portion of chromosome 8 has been observed by in situ hybridization with c-myc and thyroglobulin probes.
