Similarly, different bi-allelic mutations in FANCM were suspected in independent studies as being the causes for early menopause (Catucci et al. 2018), non-syndromic POI (Fouquet et al. 2017), and non-obstructive azoospermia (Kasak et al. 2018; Yin et al. 2019). Here, FANCM is linked to Azoospermia.
