The current perspective on genetic and epigenetic factors in sperm maturation in the epididymis.

abstract：:Multiple morphological abnormalities of the sperm flagella (MMAF) is a rare disease associated with male infertility. In our previous study, we identified a homozygous CFAP43 splice-site variant, c.3661-2delA, in a patient with MMAF. However, the mutational effect of this variant was unknown. Here, using a minigene as...
