piRNAs are crucial for transposon silencing, germ cell maturation, and fertility in male mice. Here, we report on the genetic landscape of piRNA dysfunction humans present 39 infertile men carrying biallelic variants 14 different pathway genes, including PIWIL1, GTSF1, GPAT2, MAEL, TDRD1, DDX4. In some affected men, testicular phenotypes differ from those respective knockout mice range complete loss to production a few morphologically abnormal sperm. A reduced number pachytene was detected...

Abstract Background MCM8 and MCM9 are newly proposed cancer predisposition genes, linked to polyposis early-onset cancer, in addition their association with hypogonadism. Given the uncertain range of phenotypic manifestations unclear risk estimates, this study aimed delineate molecular clinical characteristics individuals biallelic germline / variants. Methods Population allele frequencies variant carrier were calculated using data from gnomAD, a enrichment analysis was conducted across...
