Robertsonian fusion
In humans, when a Robertsonian translocation joins the long arm of chromosome 21 with the long arm of chromosomes 14 or 15, the heterozygous carrier is phenotypically normal because there are two copies of all major chromosome arms and hence two copies of all essential genes. However, the progeny of this carrier may inherit an unbalanced trisomy 21, causing Down syndrome. About one in a thousand newborns have a Robertsonian translocation. The most frequent forms … WebNov 16, 2012 · In the literature, only one case of CML patients with Robertsonian t (14;22) have been described. To our knowledge this is the first report showing a Robertsonian t (14;22) in a variant Ph involving four chromosomes and exhibiting the fusion FISH signal in a derivative chromosome 14, with masked Ph.
