WebThe extra copy of chromosome number 13 or number 18 is present in every cell in the body. Sometimes the extra number 13 or number 18 chromosome, or part of it, is attached to another chromosome in the egg or sperm. This is called a translocation. This is the only form of trisomy 13 or 18 that may be inherited from a parent. WebRobertsonian translocations between chromosomes 13 and 14 (rob[13;14]) are associated with some clinical manifestations, including male infertility and recurrent pregnancy loss (RPL). In this review, the clinical features associated with rob(13;14) translocation are discussed and the incidence rate …

In Robertsonian translocation, the two long arms of two separate acrocentric chromosomes fuse to create one chromosome. Chromosome 13 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 13 spans about 113 million base pairs (the building material of DNA) and represents between 3.5 and 4% of the total DNA in cells.
