TDP-43 iCLIP of cells transfected with UNC13A minigene

UNC13A contains a cryptic exon which is normally repressed by TDP-43. To better understand the mechanism by which TDP-43 represses this cryptic splicing, and how common SNPs (rs12973192(G) and rs12608932(C)) perturb this regulation, we transfected HEK293T cells with minigenes featuring UNC13A exons 20 and 21, and intron 20. We used two variants of the minigene: one with rs12973192(C) and rs12608932(G) (2x healthy) and the other with rs12973192(G) and rs12973192(C) (2x risk), then performed TDP-43 iCLIP on these cells. We used two replicates for each.
