| Outline of Final Research Achievements |
A comprehensive microarray analysis of the X chromosome was carried out using DNA derived from peripheral blood lymphocytes of 12 azoospermia patients with testicular volume of 5 ml or less. While covering all chromosomes with a 4 x 180 K microarray, the probes were designed at high density so that the distance between the probes was 661 bp on the X chromosome. We found significant copy number variant in the region containing 35 coding genes (33 increase, 3 decrease). There were 10 regions including 14 coding genes that showed copy number variant in common in more than two cases. It was suggested that these genes may be candidate genes for testicular growth and spermatogenesis.
