MEIG1

Chr 10

meiosis/spermiogenesis associated 1

Also known as: SPATA39, bA2K17.3

The MEIG1 protein is essential for spermiogenesis, the process of sperm cell maturation during male fertility development. Mutations in this gene cause male infertility due to defects in sperm formation, following an autosomal recessive inheritance pattern. This gene shows low constraint against loss-of-function variants, consistent with its specialized role in male reproductive function.
