Involvement in diseasei

Spermatogenic failure 10 (SPGF10)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn infertility disorder caused by spermatogenesis defects. It results in decreased sperm motility, concentration, and multiple sperm structural defects. The most prominent feature is a defective sperm annulus, a ring structure that demarcates the midpiece and the principal piece of the sperm tail.
