Human chromosome deletions in Yq11, AZF candidate genes and male infertility: history and update

Abstract excerpt

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 apparently...
