An extra G-positive band within the 9qh regions is reported as a new chromosome 9 variant. This variant may have been more prevalent than has hitherto been perceived. Due to its small size, this extra band might not be readily recognizable in routine G-staining.

D016135	Spinal Dysraphism	Congenital defects of closure of one or more vertebral arches, which may be associated with malformations of the spinal cord, nerve roots, congenital fibrous bands, lipomas, and congenital cysts. These malformations range from mild (e.g., SPINA BIFIDA OCCULTA) to severe, including rachischisis where there is complete failure of neural tube and spinal cord fusion, resulting in exposure of the spinal cord at the surface. Spinal dysraphism includes all forms of spina bifida. The open form is called SPINA BIFIDA CYSTICA and the closed form is SPINA BIFIDA OCCULTA.
