Robertsonian 13
WebRobertsonian translocations are relatively common in the general population (about 1 in 1000), the most frequent being fusion of the long arms of chromosomes 13 and 14. The significance of a Robertsonian Translocation is the risk of miscarriage or of producing children with an unbalanced chromosome make-up. Insertions 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 …
