Helen Brittain (Genomics England Curator)

Comment when marking as ready: Liebenberg syndrome is not associated with radial dysplasia, as appropriate for this panel. It causes radial metaphyseal abnormalities and elbow / wrist positioning anomalies. These are not considered in keeping with the scope of this panel.

Rebecca Foulger (Genomics England curator)

The mutations that cause Liebenberg syndrome are thought to relocate enhancers that normally promote the activity of genes involved in upper limb development to be near the PITX1 gene, where they can promote its activity. Alternatively, the mutations may remove repressors that normally turn off the PITX1 gene during upper limb development. As a result, the PITX1 gene is abnormally active during development of the upper limbs.
