TEX11 and Azoospermia: The deletion genomic region was rich in transposable elements and was prone to genomic rearrangements, as shown by a clustering of breakpoints of multiple duplications around TEX11 introns 9 and 12.109, 110, 111, 112 This loss, which was identical in both the patients with azoospermia, predicts a deletion of 79 amino acids within the SPO22 region.
