For example, meiosis-expressed gene 1 (MEIG1) is located on chromosome 10p13, and is associated with the control of spermiogenesis.[6] Sperm-associated antigen 6 (SPAG6) gene, mapped on chromosome 10 at 10p12.2, is essential for sperm flagellar motility, and is important for the maintenance of the structural integrity of mature spermatozoa.[7] The wings apart-like protein (WAPL) gene is located on chromosome 10q23.2, and is implicated in spermatogenesis.[8] A breakpoint at 10q24 is also linked with impaired spermatogenesis and recurrent spontaneous abortion.[9]. The gene discussed is SPAG6; the disease is abortion.
