The Gardner-Silengo-Wachtel or genito-palato-cardiac syndrome: male pseudohermaphroditism with micrognathia, cleft palate, and conotruncal cardiac defect

We report on two sib fetuses with similar abnormalities detected prenatally by ultrasound. The first fetus had micrognathia, was without cleft palate, and had low-set ears, double outlet right ventricle with a ventricular septal defect, and 46,XY gonadal dysgenesis. The second sib fetus was born with cleft lip and palate, micrognathia, transposition of the great vessels, ventricular septal defect, a right-sided aorta arch, and bilateral cystic kidneys with hypospadias. We were able to identify 11 additional cases in the literature with similar findings. We think this set of defects is a recognizable syndrome that appears to be inherited either as an autosomal recessive or as an X-linked recessive and may overlap with the Smith-Lemli-Opitz syndrome.
