William Rees Brebner Robertson (31 May 1881 - 15 March 1941) was an American zoologist and early cytogeneticist who discovered the chromosomal rearrangement named in his honour, Robertsonian translocation, the most common structural chromosomal abnormalities seen in humans that result in syndromes of multiple malformations, including trisomy 13 Patau syndrome and trisomy 21 Down syndrome.
Chromosomal reciprocal translocation of the 4th and 20th chromosome. In genetics, chromosome translocation is a phenomenon that results in unusual rearrangement of chromosomes. This includes balanced and unbalanced translocation, with two main types: reciprocal, and Robertsonian translocation.
The extra chromosome 21 material that causes Down syndrome may be due to a Robertsonian translocation. The long arm of chromosome 21 is attached to the long arm of another chromosome, often chromosome 14 [46,XX,t(14;21)] or itself [called an isochromosome, 45,XX,t(21;21)(q10;q10)] as seen in the translocation karyotype figure.
