[Microdeletion of chromosome Y in male infertility: role of the DAZ gene].

Microdeletions of the Y chromosome represent the most frequent cause of male infertility, being responsible for 10-15% of cases of azoospermia or severe oligozoospermia. Such mutations localize in one or more loci named azoospermia factor (AZF) a, b and c. Mutations more frequently involve the DAZ gene in AZFc, and could determine both azoospermia and… CONTINUE READING
