Has a role in spermatogenesis and oogenesis (PubMed:8244010). Might have a role in triglyceride homeostasis (PubMed:25409104). Probably by regulating lipid storage and catabolism, plays a role in neuronal function (PubMed:25409104). Accumulation of spermatocytes with cytoplasmic abnormalities. Early spermatocytes are filled with small, refractile cytoplasmic inclusions, late spermatocytes often contain up to three hook-shaped structures in the cytoplasm. Testes are short with incomplete coiling. The sheath of pigment cells that covers the muscle layer surrounding the testis frequently peels away, particularly from the region near the tip. Female fertility is also reduced, ovaries are small and misshapen. Belongs to the cueball family.
