| robertsonian translocation |
A type of translocation exclusive to the acrocentric chromosomes (13,14,15,21,22), in which two chromosomes join at or near their centromeres. This is effectively a fusion between two whole chromosomes rather than an exchange of material as in reciprocal translocation.

| robertsonian t. |
translocation involving two of the acrocentric chromosomes (13, 14, 15, 21, and 22), which fuse at the centromere region and lose their heterochromatic short arms. A carrier of a balanced robertsonian translocation involving chromosome 14 and 21 has a virtually complete chromosomal complement but only 45 chromosomes (including the translocation chromosome), is phenotypically normal, but risks producing offspring with trisomy 21 (translocation Down syndrome). See Plate 1.
