Chromosomal 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 کاملSperm FISH studies in seven male carriers of Robertsonian translocation t(13;14)(q10;q10).
BACKGROUND Robertsonian translocation t(13;14) is one of the most common structural reorganization in humans, but meiotic segregation studies in these carriers are still limited. The segregation pattern of the chromosomes involved, the possible influence of the translocated chromosomes on the synapsis and disjunction of other chromosome pairs [interchromosomal effects (ICE)] and the rates of un...
متن کاملChromosome Segregation Analysis in Human Embryos Obtained from Couples Involving Male Carriers of Reciprocal or Robertsonian Translocation
The objective of this study was to investigate the frequency and type of chromosome segregation patterns in cleavage stage embryos obtained from male carriers of Robertsonian (ROB) and reciprocal (REC) translocations undergoing preimplantation genetic diagnosis (PGD) at our reproductive center. We used FISH to analyze chromosome segregation in 308 day 3 cleavage stage embryos obtained from 26 p...
متن کاملSperm segregation analysis of a (13;22) Robertsonian translocation carrier by FISH: a comparison of locus-specific probe and whole chromosome painting.
BACKGROUND The t(13;22) Robertsonian translocation constitutes a rare form of rearrangement between acrocentric human chromosomes. Most of the meiotic segregation studies of human Robertsonian translocations have been performed on common t(13;14) and t(14;21) translocations. Analysis of the chromosomal constitution in sperm of Robertsonian translocation carriers is of great interest for assessi...
متن کاملTransmission ratio distortion in offspring of mouse heterozygous carriers of a (7.18) Robertsonian translocation.
Transmission ratio distortion (TRD) is defined as a significant departure from expected Mendelian ratios of inheritance of an allele or chromosome. TRD is observed among specific regions of the mouse and human genome and is frequently associated with chromosome rearrangements such as Robertsonian (Rb) chromosomes. We intercrossed mice heterozygous for a (7.18) Rb translocation and genotyped chr...
