Robertsonian translocation and infertility
WebRobertsonian translocations (RTs) are among the most common types of chromosome rearrangements, specifically involving the acrocentric chromosomes in humans. These rearrangements can be classified into two types: (1) common RTs such as the der (13;14) and the der (14;21), and (2) rare RTs. WebThe most common translocations reported are t (7;13), t (10;14), and t (3;15), observed, respectively, in 13, 8, and 8 subjects.
