Robertsonian Translocation and Its Effect on Fertility in Japanese Black Cattle
To confirm the distribution of chromosome abnormalities and their effects on fertility, a cytogenetic survey was carried out in five different herds of Japanese Black Cattle. The chromosome abnormality most frequently observed was the 7/21 Robertsonian translocation. This translocation was observed in a local herd at a fairly high frequency of 10.9% due to continuous use of the carrier bulls in...
متن کاملChromosomal segregation in spermatozoa of 14 Robertsonian translocation carriers.
Male carriers of Robertsonian (Rob) translocations can have fertility problems associated with low sperm counts and abnormal sperm morphology. In this study, spermatozoa from 14 Rob translocation carriers, seven der(13;14), two der(13;15), two der(14;15), two der(14;21) and one der(21;22), were tested by fluorescence in-situ hybridization (FISH) for the chromosomes involved, to study meiotic se...
متن کاملThe 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 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 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...
