FOXP3 pathogenic variants cause male infertility through affecting the proliferation and apoptosis of human spermatogonial stem cells.

ABSTRACT: Genetic causes of male infertility that is associated with aging are largely unknown. This study was designed to identify novel pathogenic variants of FOXP3 gene causing azoospermia. One homozygous (c.155 G > T) pathogenic variant of FOXP3 was identified in nine non-obstructive azoospermia patients, and one heterozygous (c.691 C > A) of FOXP3 was found in one non-obstructive azoospermia patient. Pedigrees studies indicated that the homozygous (c.155 G > T) FOXP3 pathogenic variant was inherited, while heterozygous (c.691 C > A) FOXP3 pathogenic variant was acquired. Human testis carrying pathogenic variant exhibited abnormal spermatogenesis. FOXP3 protein was expressed at a lower level or undetected in spermatocytes of mutant testis of non-obstructive azo
