Study on the vertical transmission of Y chromosome microdeletions from father to son / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the Y chromosome microdeletions in the family of the infertile male and to study on the vertical transmission of Y chromosome microdeletions from father to son.</p><p><b>METHODS</b>The peripheral blood of infertile patients' family male members was extracted and analyzed with modified multiplex PCR. The infertile family tree was drawn according to the results.</p><p><b>RESULTS</b>Two cases in twelve investigated families had azoospermia factor (AZFc) microdeletion heredity. The others had no heredity.</p><p><b>CONCLUSION</b>AZFc microdeletion of the Y chromosome can be transmitted to the male offspring naturally,and the same deletion can result in different phenotypes in different individuals.</p>
