WebFeb 16, 2024 · Robertsonian translocations are one of the most common structural chromosomal rearrangements, consisting of a fusion of the long arms of two acrocentric chromosomes. In humans, this rearrangement occurs in the five pairs of acrocentric chromosomes, comprising chromosomes 13, 14, and 15 (group D) and 21 and 22 (group G). 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. isle of man bus timetable 2021
