To read the full abstract: Nat Med. 2019 Mar;25(3):439–447.Prenatal screening for trisomy 21, trisomy 18, trisomy 13, and sex chromosome aneuploidies can be performed using next-generation sequencing of cell-free DNA (cfDNA) in the maternal circulation. This article describes a new non-invasive prenatal screening (NIPS) approach for the detection of de novo or paternally inheri...

Brief summary: In this in vivo study, Xia et al. demonstrate that AAV-mediated gene therapy recovers testosterone levels, restarts sexual development, restores spermatogenesis, and produces fertile offspring in a mouse model of Leydig cell failure (LCF).A null mutation in the gene encoding luteinizing hormone/choriogonadotrophin receptor (Lhcgr) causes a hereditary LCF in mice which is characterized by a reduction in testosterone levels...
