The long arms then fuse forming a single chromosome. The loss of the satellites of acrocentric chromosomes does not cause clinical problems, as these satellites contain genomic material which is not essential for life.Learn about Robertsonian Translocation, a type of Down Syndrome called ROB in an animationDown syndrome Non Disjunction form https://youtu.be/kOZ6d8iOjfgMosi...

This type of translocation lead to viable...The most common translocation in humans involves chromosomes 13 and 14 and is seen in about 0.97 / 1000 newborns. For example, carriers of Robertsonian translocations involving chromosome 21 have a higher risk of having a child with Down syndrome. This is known as a 'translocation Downs'.The total chromosome number in a Robertsonian translocation carrier is therefore reduced to 45. As no gain or loss of important genetic material occurs, Robertsonian translocation carriers are normal.Tools Share Abstract Robertsonian translocations 13/14 are the most common chromosome rearrangements in humans. However, most studies aimed at determining risk figures are more than 20 years old. Their results are often contradictory regarding important topics in genetic counseling such as infertility and unfavorable pregnancy outcomes.For example, a specific reciprocal translocation takes place between chromosomes 1 and 19.
