Jasmine Chew changed review comment from: i) PMID: 23582645- 3 heterozygous missense variants in 3 unrelated infertile men, and studies in transfected CHO-K1 cells revealed reduced interactions with CFTR and complete failure of the all three mutant to activate CFTR-dependent anion transport. Immunoblot analysis also showed that the mutant protein was significantly less abundant than wildtype and the decreased abundance of the mutant protein results from instability and proteasomal degradation. ii) PMID: 34923715- Compound heterozygous variants in two unrelated infertile Chinese men with severe asthenozoospermia. The sperm motility of these homozygous probands was severely reduced, compared to the moderately reduced motility of sperm from the previously reported heterozygous probands (confirmed by immunoblot), consistent with SLC26A8 being the cause of their infertility phenotype, iii) PMID: 35181959- 3 heterozygous variants ( 2-bp deletion, V731I, 1-bp deletion) in 3 unrelated infertile men with asthenoteratozoospermia, and although transfection study showed a significantly reduction of SLC26A8 expression to nearly absence in transfected HEK293 cells, immunostaining of patient sperm showed no difference in SLC26A8 expression compared to control sperm and western blot analysis of spermatozoa lysates confirmed the similar expression of SLC26A8 between patient and control sperm. Also mentioned that previous studies (PMID: 22121115 and PMID: 17517695) had shown that Slc26a8 +/- mice were fertile, whereas Slc26a8-null mice were infertile, the authors suggested that heterozygous SLC26A8 variants might not be the direct cause of the asthenoteratozoospermic phenotype observed in infertile men, and that SLC26A8-associated male infertility is likely an autosomal recessive disorder.
