- Type IV (Beemer-Langer): median cleft lip and ambiguous genitalia in some 46,XY individuals.
- Heart defects, polycystic kidneys, brain malformations and intestinal atresia.
- Detailed ultrasound examination.
- If pregnancy continues, follow-up should be standard.
- Standard obstetric care and delivery.
- The condition is lethal due to severe pulmonary hypoplasia.
- Autosomal recessive inheritance: 25%.
