Human male infertility and Y chromosome deletions: role of the AZF-candidate genes DAZ, RBM and DFFRY.
Microdeletions in Yq11 overlapping three distinct 'azoospermia factors' (AZFa-c) represent the aetiological factor of 10-15% of idiopathic azoospermia and severe oligozoospermia, with higher prevalence in more severe testiculopathies, such as Sertoli cell-only syndrome. Using a PCR-based screening, we analysed Yq microdeletions in 180 infertile patients affected by idiopathic Sertoli cell-only ...
متن کاملHuman chromosome deletions in Yq11, AZF candidate genes and male infertility: history and update.
Human chromosome deletions in Yq11 seem to occur frequently as de novo mutation events in men with idiopathic azoospermia or severe oligozoospermia. However, the molecular extensions of these deletions are variable. They can be large and therefore visible under the microscope or small, not visible under the microscope, and containing the deletion of one or more DNA loci recently mapped in an ap...
متن کاملThe role of Y chromosome deletions in male infertility.
Male infertility affects approximately 2-7% of couples around the world. Over one in ten men who seek help at infertility clinics are diagnosed as severely oligospermic or azoospermic. Recent extensive molecular studies have revealed that deletions in the azoospermia factor region of the long arm of the Y chromosome are associated with severe spermatogenic impairment (absent or severely reduced...
متن کاملY chromosome and male infertility.
Recent genome analysis of the Y chromosome has increased the number of genes found on this chromosome markedly. Many of these genes in the part of the Y chromosome that does not undergo recombination with the X chromosome are members of gene families. Evolutionary considerations imply that genes on the Y chromosome will degenerate unless they have male advantageous or female deleterious functio...
متن کاملanalysis of candidate genes has proposed the role of y chromosome in human prostate cancer
background prostate cancer is a serious genetic disease known as the first widespread cancer in men, yet the molecular changes required for the cancer progression is not fully understood. availability of high-throughput gene expression data has led to the development of various computational methods for the identification of critical genes involved in the cancer. methods in this paper, we show ...
