Background: Recurrent pregnancy loss is a form of infertility with at least three consecutive pregnancy losses or more. Y chromosome microdeletions are a class of most likely genetic factors that occur in a special zone of Y chromosome which is named azoospermia factor region. The purpose of this study was to analyze the presence of Y chromosome complete microdeletions in male partner of couple...
A Y;12 translocation, resulting in extra Yq material and partial monosomy 12p, was found in a 7 1/2 year old boy. He showed growth and mental retardation and several of the congenital anomalies seen in the 12p deletion syndrome. LDHB activity, the gene for which is located at 12p12, was normal in serum, in accordance with the suspected 12p13 deletion in the patient.
At present the pathogenesis and therapeutic effect of chronic myelomonocytic leukemia (CMML) is still not very clear. There are no specific molecular biology characteristics in it. We report a novel deletion in the Yq chromosome of a patient with CMML, as well as the treatment and prognosis, and review the relevant literature, and put forward that the Y chromosome abnormality may be involved in...
BACKGROUND The mitotic and meiotic behaviour of a transmitted ring Y [r(Y)] chromosome from a father to his Klinefelter syndrome (KS) son, and the mechanism of ring formation are analysed herein. To our knowledge, this is the first reported case of natural transmission of an r(Y). METHODS AND RESULTS Amplification of X chromosome polymorphisms by PCR showed that the KS was of paternal origin....
In common with other mammalian sex chromosomes, the mouse sex chromosomes are enriched for genes with male-specific function such as testis genes. However, in mouse there has been an unprecedented expansion of ampliconic sequence containing spermatid-expressed genes. We show via a phylogenetic analysis of gene amplification on the mouse sex chromosomes that multiple families of sex-linked sperm...
A logical theory of regular double or multiple recurrence of eventualities, which are regular patterns of occurrences that are repeated, in time, has been developed within the context of temporal reasoning that enabled reasoning about the problem of coincidence. i.e. if two complex eventualities, or eventuality sequences consisting respectively of component eventualities x0, x1,....,xr and y0, ...
Microdeletions in Yq are associated with defects in spermatogenesis, while those in the AZF region are considered critical for germ cell development. We examined microdeletions in the Y chromosomes of patients attended at the Laboratory of Human Reproduction of the Clinical Hospital of the Federal University of Goiás as part of a screening of patients who plan to undergo assisted reproduction. ...
