Overview

Pathophysiology

  • Spina bifida is a congenital malformation in which the spinal column is split (bifid) as a result of failed closure of the embryonic neural tube, during the fourth week post-fertilization.[1]
  • In normal infants, the neural tube closes by the end of the 4 week of conception, but in patients with spina bifida, some parts of the neural tube fails to develop or close that causes defects in the spinal cord and in the vertebral bones.
  • Spina bifida also may be classified according to the tyoe of the vertebrate defect into 2 subtypes:
    • Spina bifida occulta: In this type of spina bifida, the defect of vertebrate is covered by skin ("Occulta" means "hidden"). The spinal cord does not stick out through the skin, although the skin over the lower spine may have a patch of hair, a birthmark, or a dimple above the groove between the buttocks.[1]
    • Spina ifida aperta: In this type of spina bifida , the defect is widely open and is sub classified into 2 types: Meningocele and Myelomeningocele.[1]

Pathogenesis

Genetics

he candidate genes studied include. Many and maintain planar cell polarity have also been tested as candidates.

[Disease name] is transmitted in [mode of genetic transmission] pattern.[3]

OR

The development of spina bifida may be the result of multiple genetically defect in the genes important in the metabolism of:[4]

Other genes which may be contributed in the development of the spina bifida include:

Associated Conditions

Conditions associated with spina bifida include:
