Diverse monogenic subforms of human spermatogenic failure
Nagirnaja, Liina; Lopes, Alexandra M.; Charng, Wu-Lin; Miller, Brian; Stakaitis, Rytis; Golubickaite, Ieva; Stendahl, Alexandra; Luan, TianpengchengNon-obstructive azoospermia (NOA) is the most severe form of male infertility and typically incurable. Defining the genetic basis of NOA has proven chal lenging, and the most advanced classification of NOA subforms is not based on genetics, but simple description of testis histology. In this study, we exome sequenced over 1000 clinically diagnosed NOA cases and identified a plausible recessive Mendelian cause i...
Bi-allelic Mutations in M1AP Are a Frequent Cause of Meiotic Arrest and Severel...
Wyrwoll, Margot J.; Temel, Şehime G.; Nagirnaja, Liina; Oud, Manon S.; Lopes, Alexandra M.; van der Heijden, Godfried W.; Heald, James S.; Rotte, NadjaMale infertility affects ∼7% of men, but its causes remain poorly understood. The most severe form is non-obstructive azoospermia (NOA), which is, in part, caused by an arrest at meiosis. So far, only a few validated disease-associated genes have been reported. To address this gap, we performed whole-exome sequencing in 58 men with unexplained meiotic arrest and identified the same homozygous frameshift variant...
