The Survey of Double Robertsonian Translocation 13q; 14q in the Pedigree of 44; XX Woman: A Case Report
Robertsonian translocations (RBT) are associated with an increased risk of aneuploidy. Single RBT carriers are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. However, double Robertsonian translocations (DRBT), in which two balanced RBT occur simultaneously, are an extremely rare condition. A 9-year-old mentally normal girl with mu...

متن کاملSimultaneous Occurrence of Turner Syndrome and Robertsonian Translocation in a Girl with Short Stature: A Case Report
Short stature is an important clinical feature of Turner syndrome (TS). In this report, a girl with short stature suspected to have Turner syndrome underwent cytogenetic analysis, which confirmd Turner syndrome by observing sex chromosomal monosomy using the karyotype test. In addition to Turner syndrome, Robertsonian (ROB) translocation t(13;14) was detected. As recommended by a genetic counse...
متن کاملCd branding studies in a homologous Robertsonian 13;13 translocation.
A phenotypically normal female with a history of two miscarriages was found to have the karyotype 45,XX,t(13p:13p). C banding showed the translocation to have two regions of centromeric constitutive heterochromatin, silver staining showed an active NOR in 60% of the cells screened, and Cd banding studies showed a single Cd band with absence of the Cd band at the suppressed centromere.
متن کاملBreakpoint diversity illustrates distinct mechanisms for Robertsonian translocation formation.
Robertsonian translocations are the most common chromosomal rearrangements in humans. The vast majority of the ten possible nonhomologous types of Robertsonian translocations ascertained are rob(13q14q) and rob(14q21q). Recombination between homologous sequences on nonhomologous chromosomes has been proposed as a mechanism leading to the preferential formation of rob(13q14q) and rob(14q21q). Ho...
