Neuralrohrdefekt (NTD)
Spinal dysraphism (NTD)
General description
Neural tube defects result from abnormal closure or development of the neuronal tube during embryogenesis. A genetic variant has been found to cause spinal dysraphism, which is a non-progressiv ataxia and is characterised by the following symptoms: abnormal hair streams along the back, kinked tails, scoliosis in the lumbar spinal region, paraparesis, “bunny-hopping”, crouched stance.

Detailed description
Neural tube defects result from abnormal closure or development of the neuronal tube during embryogenesis. In the Weimaraner breed, a mutation of the regulatory homebox gene NKX2-8, which is expressed in the developing tube, could be found to be associated with the neural tube defect, termed spinal dysraphism. The spinal dysraphism is a non-progressiv ataxia and is characterised by the following symptoms: abnormal hair streams along the back, kinked tails, scoliosis in the lumbar spinal region, paraparesis, “bunny-hopping”, crouched stance.
