Robertsonian 13 14 translocation
WebAbstract: Robertsonian translocations (ROBs) are whole arm rearrangements involving the acrocentric chromosomes 13-15 and 21-22 and carriers are at increased risk for aneuploidy and thus uniparental disomy (UPD). Chromosomes 14 and 15 are imprinted with expression of genes dependent on the parental origin of the chromosome. WebRobertsonian translocations are a specific class of translocations in which two acrocentric chromosomes fuse at their centric ends (45). In humans, chromosomes 13, 14, 15, 21, and 22 are acrocentric, and all of these chromosomes are associated with …
