Seabra et al. [50] described a cryptorchidism patient with azoospermia presenting a microdeletion at 11p13 in TCP11L1. Liu et al. [51] found that TCP11L1 shares its functional domain with and has similar subcellular localization to the TCP11 protein, suggesting that the two proteins have a similar role in spermatogenesis. This evidence concerns the gene TCP11 and Azoospermia.
