Relationships to Other Disease States and Syndromes

  • Familial neural tube defects: In patients with occult spinal dysraphism, there may be a greater likelihood of family members having open neural tube defects. However, this is not specific for patients with tethered cords with a normally positioned conus.
  • Other syndromes: Occult spinal dysraphism is also associated with various syndromes including caudal agenesis, cloacal extrophy, VATER and VATER-like syndromes.
