title: A new chromosome 9 variant: an extra band within the 9qh region.
abstract: 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.
