‘new’ families

Durham, NC, USA

An article about a new American family (6 people, 3 generations) with Wagner was published in November 2009 by the people from Duke’s eye hospital in Durham, North Carolina. They reported a unique base pair substitution in intron 8: c.9265+1G>T. This is the same base pair as in the families from Zürich and Cambridge. only with them the G was replaces by an A. The authors speak of a mutational Hot-Spot:

Nijmegen, the Netherlands

Through this website another Dutch family (30 people) came about. None of them was ever mentioned in a publication. A proband has been tested and it appeared that this family also belongs to the pedigree of the founder mutation (c.4004-5T>C)

Paris, France

In the meeting of the French Society of Ophthalmology (SFO) in May 2009 a second French family (9 people, 6 with retinal detachment, 5 with a raised IOP) with Wagner syndrome was reported. A new phenomenon they reported was a chronic disrupture of the blood-aqueous barrier (bab). Normally this happens during inflammation. But apart from one case with uveïtis, this was not a feature in the other eight people. There can be a correlation with elevated intraocular pressure. As the protein and other components that appear in the aqueous when the bab is disrupted can influence the aqueous outflow.
