Study question: Do the genetic determinants of idiopathic severe spermatogenic failure (SPGF) differ between generations? Summary answer: Our data support that the genetic component of idiopathic SPGF is impacted by dynamic changes in environmental exposures over decades. What is known already: The idiopathic form of SPGF has a multifactorial etiology wherein an interaction between genetic, epigenetic, and envi...
A polymorphic inversion that lies on chromosome 17q21 comprises two major haplotype families (H1 and H2) that not only differ in orientation but also in copy-number. Although the processes driving the spread of the inversion-associated lineage (H2) in humans remain unclear, a selective advantage has been proposed for one of its subtypes. Here, we genotyped a large panel of individuals from previously overlooked...
Objective: We have recently performed an array-based genome-wide analysis of structural variants in a cohort of patients with non-obstructive azoospermia (NOA) and found a cryptic deletion of approximately 1Mb in 11p13, spanning the WT1 gene but not PAX6, in a Portuguese patient with clinical history of cryptorchidism during childhood?. Here we performed the molecular characterization of this novel deletion, to...
