SOX30 and male infertility: Another example is SOX30 which is atranscription factor required for late mouse spermatogenesis (KO of which results inarrested spermatid development), and although SOX30 is involved in humanspermatogenesis, mutations in SOX30 did not necessarily uniformlyresult in male infertility due to a uniform mechanism of spermatid developmentalarrest, indicating species-specific differences in compensatory mechanisms (Zhang et al. 2018, Bush et al. 2024).
