The paper identifies a large amplified intronless gene, Laidx, on the X chromosome in mice, shows its evolutionary origin from a horizontal gene transfer, and finds no reproductive defects in its absence.

The paper investigates whether palindromic structures on the X chromosome are necessary for post-meiotic gene expression and fertility in male mice, finding that gene expression and fertility are unaffected by deletions of these regions.
