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 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 کاملa robertsonian translocation rob (14;15) (q10:q10) in a patient with recurrent abortions: a case report
introduction: robertsonian translocation is one of the major chromosomal rearrangements with a prevalence rate of 0.1% of the general population and 1% of the infertile population. in this report, we present a nonhomologous robertsonian translocation in a female patient with a history of repeated abortions. case presentation: a couple with the complaint of repeated abortions was admitted in the...
متن کاملA rare non-Robertsonian translocation involving chromosomes 15 and 21.
CONTEXT Robertsonian translocations (RT) are among the most common balanced structural rearrangements in humans and comprise complete chromatin fusion of the long arm of two acrocentric chromosomes. Nevertheless, non-Robertsonian translocation involving these chromosomes is a rare event. CASE REPORT We report a de novo unbalanced translocation involving chromosomes 15 and 21. The newborn was ...
