Several recurrent genetic mutations have been reported to be associated with abnormal sperm morphology, but the genetic basis of tapered-head sperm is not well understood. In this study, whole-exome sequencing (WES) identified a homozygous WD repeat domain 12 (\n                    <jats:italic toggle=\"yes\">WDR12<\/jats:italic>\n                    ; p.Ser162Ala\/c.484T&gt;G) variant in an infertile patient with tapered-head spermatozoa from a consanguineous Chinese family. Bioinformatic analysis predicted this mutation to be a pathogenic variant. To verify the effect of this variant, we analyzed WDR12 protein expression in spermatozoa of the patient and a control individual, as well as in the 293T cell line, by Western blot analysis, and found that WDR12 expression was significantly downregulated. To understand the role of normal WDR12, we evaluated its mRNA and protein expression in mice at different ages. We observed that\n                    <jats:italic toggle=\"yes\">WDR12<\/jats:italic>\n                    expression was increased in pachytene spermatocytes, with intense staining visible in round spermatid nuclei. Based on these results, the data suggest that the rare biallelic pathogenic missense variant (p.Ser162Ala\/c.484T&gt;G) in the\n                    <jats:italic toggle=\"yes\">WDR12<\/jats:italic>\n                    gene is associated with tapered-head spermatozoa.
