One of the genes implicated in the ciliopathies is WDR19, which can lead to several syndromic diseases that may manifest with a form of retinal degeneration.

We measured the response to flashes (9 flash strengths in total between 0.12 and 29.76 cd.s/m² while doubling the strength at each step; 5 ms flash duration) on a steady background (24 cd/m²) and on a 1 Hz modulating background (24 cd/m² mean luminance; 100% contrast).
