[Y chromosome microdeletions in male infertility].
A genetic basis of infertility may exist in many men currently classified as having idiopathic infertility. Approximately 7% of infertile men harbour submicroscopic deletions of the Y chromosome that are not detectable on routine karyotype. Two candidate gene families, namely the RNA-binding motif-containing gene family, and the deleted-in-azoospermia gene family, have been cloned by deletion m...
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 کاملHuman 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 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 کاملDetection of Y chromosome microdeletions and mitochondrial DNA mutations in male infertility patients.
Infertility affects about 10-15% of all couples attempting pregnancy with infertility attributed to the male partner in approximately half of the cases. Proposed causes of male infertility include sperm motility disturbances, Y chromosome microdeletions, chromosomal abnormalities, single gene mutations, and sperm mitochondrial DNA (mtDNA) rearrangements. To investigate the etiology of decr...
