Variants in GCNA, X-linked germ-cell genome integrity gene, identified in men w...
Hardy, Jimmaline J.; Wyrwoll, Margot J.; Mcfadden, William; Malcher, Agnieszka; Rotte, Nadja; Pollock, Nijole C.; Munyoki, Sarah; Veroli, Maria V.Male infertility impacts millions of couples yet, the etiology of primary infertility remains largely unknown. A critical element of successful spermatogenesis is maintenance of genome integrity. Here, we present a genomic study of spermatogenic failure (SPGF). Our initial analysis (n=176) did not reveal known gene-candidates but identifed a potentially signifcant single-nucleotide variant (SNV) in X-linked ger...
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...
