FGF8 and cryptorchidism: Zeidler and coworkers identified two FGF8 heterozygous missense variants (p.Gly29_Arg34dup, p.Pro26Leu) in two different patients by conducting a targeted FGF8 sequencing on 78 VATER/VACTERL and VATER/VACTERL-like individuals, and both patients presented with bilateral cryptorchidism.
