Chromosomal Analysis of Couples with Repeated Spontaneous Abortions in Northeastern Iran
Background Cytogenetic study of reproductive wastage is an important aspect in determining the genetic background of early embryogenesis. Approximately 15 to 20% of all pregnancies in humans are terminated as recurrent spontaneous abortions (RSAs). The aim of this study was to detect chromosome abnormalities in couples with RSAs and to compare our results with those reported previously. Materia...
متن کاملA Case Report of a Novel Balanced Reciprocal Translocation t(2;14)(q11;q24) in a Young Woman with Two Pregnancy Losses
Reciprocal chromosome translocations, especially balanced rearrangements are known to be one of the main causes of recurrent miscarriage. In this case report, we performed the clinical and cytogenetic analysis on a young couple with two pregnancy losses. Though the couple had a normal clinical study, the cytogenetic analysis revealed a balanced reciprocal translocation of t(2;14)(q11;q24) where...
متن کاملDominant X-chromosome nondisjunction mutants of Caenorhabditis elegans.
Eight dominant X-chromosome nondisjunction mutants have been identified and characterized. Hermaphrodites (XX) heterozygous for any one of the mutations produce 20-35% male (XO) self-progeny compared with the wild-type frequency of 0.2%. Seven of the eight mutants carry X-autosome translocations. Three of these, represented by mnT2, involve linkage group (LG) II and show severe crossover suppre...
متن کاملBalanced Reciprocal Translocation t(X;1) in a Girl with Tall Stature and Primary Amenorrhea
AbstractChromosomal translocations constitute one of the most important, yet uncommon, causes of primary amenorrhea and gonadal dysgenesis. Although X-autosome translocations are frequently associated with streak gonads and clinical features of the Turner syndrome, the majority of X-autosome carriers may present with a variable phenotype, developmental delay, and recognizable X-linked syndrome ...
متن کاملMost Uv-Induced Reciprocal Translocations in SORDARIA MACROSPORA Occur in or near Centromere Regions.
In fungi, translocations can be identified and classified by the patterns of ascospore abortion in asci from crosses of rearrangement x normal sequence. Previous studies of UV-induced rearrangements in Sordaria macrospora revealed that a major class (called type III) appeared to be reciprocal translocations that were anomalous in producing an unexpected class of asci with four aborted ascospore...
