We ond was roughly 500 genes whose expression levels changed through the course of pregnancy in the women who had pre clamsia versus those who didn't. And so we think that that panel of genes could form the basis of a diagnostic screen to help understand who's at risk. To really understand i there is n be clinical value, a large, blind trial has to be done. But it's, i think, an exciting proof of principle that indicates what might be possible in the field.
