It was obtained that the rs1801320 SNP in RAD51 is correlated with an increased risk of ovarian (Smolarz et al., 2013; Romanowicz-Makowska et al., 2012), breast (Sun et al., 2011), colorectal (Nissar et al., 2014), endometrial (Michalska et al., 2014), head and neck (Sliwinski et al., 2010), myelodysplastic syndrome (He et al., 2014), Fuchs and keratoconus endothelial corneal dystrophy (Synowiec et al., 2013), as well as triple-negative breast cancer (Smolarz et al., 2013) in several ethnicities. This evidence concerns the gene RAD51 and corneal endothelial dystrophy.
