ABSTRACT
This report describes a case of mosaic Down syndrome due to an unusual karyotype in a patient conceived by assisted reproductive techniques and cryopreservation. The chromosomal complement consists of two different cell lines, one predominantly trisomic with a derivative chromosome due to a Robertsonian translocation (21;21) and another carrying a ring chromosome 21. The present work analyses the different mechanisms that could have led to mosaicism.
