SLC26A3 and Infertility: We observed that, altogether, 25 men with idiopathic infertility carried heterozygous variants in the coding region of the SLC26A3 gene (GenBank: NM_000111.2), the frequency of heterozygosity being 3.7-fold higher in infertile men than in controls (8.8% vs. 2.4%, respectively; P = 0.007) (Table 1).
